During secondary process shutdown, when nvme device
would get detached, it would trigger env_dpdk to
send rte_eal_hotplug_remove event for the corresponding
BDF. But this isn't valid from a secondary process -
we can only attach/detach from the primary process.
Usually this would just result in a bunch of annoying
print messages as the secondary and primary process
sent rte messages between each other. But occasionally
one of the response messages from the primary process
could arrive just as the secondary process was going
through rte_eal_cleanup. The message would get
kicked to the DPDK intr thread, we would do bus_cleanup
which frees all of the PCI state, and then the message
would execute on the intr thread causing seg faults,
use-after-free or some other violation.
It's possible some kind of cleanup should be
implemented in DPDK, but for now, let's just not
induce incorrect behavior from SPDK, and don't send
the hotplug_remove messages from a secondary
process.
Fixes issue #2651.

test/ublk/ublk.sh 256
will now create 256 ublk devices, to try to test
the ctrlr_cmd queueing logic when the ctrl uring
runs out of sqes.
It's actually difficult to induce the condition,
since the kernel SQPOLL thread can usually keep
up with the SPDK process submitting the control
commands. The best way to induce it is by
*not* stopping the disks at the end of a test
with a lot of disks, and letting ublk_destroy_target
stop all of them at once. Even then, with the
ublk logging enabled, even that extra delay for
each commands opcode is enough to help the
SQPOLL thread to keep up. Commenting out the
first UBLK_DEBUGLOG in ublk_ctrl_cmd() does help
it run out of sqes, at least in my setup.

This is a workaround but is necessary to fix the github issue #2874.
Due to some unknown reason, in nightly test with Intel e810 NICs
when a qpair is created with synchronous mode and connection errors
are detected, the qpair is destroyed even if requests for the qpair are
still inflight. Then, nvme_rdma_process_recv_completion() causes NULL
pointer acccess. To fix this NULL pointer access, change
nvme_rdma_process_recv_completion() to return immediately if rsp->rqpair
is NULL. Add a TODO comment to find a root cause and really fix the
issue.
One of the fixes for the issue #2874.

Supporting SRQ caused two kinds of memory leaks. Fix both in this patch.
1. rqpair->rsps was leaked and null pointer access occurred
An error was detected during the nightly nvmf_delete_subsystem test.
The NVMe perf tool crashed with SIGABRT.
The reason of the crash was
nvme_rdma.c:2504:2: runtime error: member access within null pointer of type 'struct nvme_rdma_rsps'
This was caused by clearing rqpair->rsps before freeing rqpair->rsps.
rqpair->rsps should have been held until rqpair->rsps is freed. However,
when we support SRQ, rqpair->rsps was cleared when releasing rqpair->poller
by mistake. rqpair->rsps should be cleared only if SRQ is enabled because
in this case rqpair uses rsps of rqpair->poller.
2. rqpair->reqs and rsps are leaked for admin qpair at controller reset
To avoid unnecessary alloc and free for rqpair->rsps when enabling SRQ,
nvme_rdma_create_reqs() and nvme_rdma_create_rsps() were moved to
nvme_rdma_connect_established().
On the other hand, nvme_rdma_free_reqs() and nvme_rdma_free_rsps() were
called by nvme_rdma_ctrlr_delete_io_qpair().
However, at controller reset, admin qpair was just disconnected and
reconnected. In this case, nvme_rdma_create_reqs() and
nvme_rdma_create_rsps() were called again without calling
nvme_rdma_free_reqs() and nvme_rdma_free_rsps().
Hence, memory leak occurred.
To fix the memory leak, move nvme_rdma_free_reqs() and nvme_rdma_free_rsps()
from nvme_rdma_ctrlr_delete_io_qpair() to nvme_rdma_qpair_destroy().

Avoid hotplug application timeouts on machines
with multiple NVMe drives by scaling app run time
to number of NVMe drives.
Furthermore, change the way we wait for hotplug
app initialization by using "perform_tests" RPC,
and termination by starting it via timeout command.
