763d058efd nvmf: remove accept poller from generic layer
Not every transport requires accept poller - transport specific
layer can have its own policy and way of handling new connection.
APIs to notify generic layer are already in place
 - spdk_nvmf_poll_group_add
 - spdk_nvmf_tgt_new_qpair

Having accept poller removed should simplify interrupt mode impl
in transport specific layer.

Fixes issue #1876

2d53d32872 nvmf/vfio-user: Fix doorbell polling not working on some ARM platform
On aarch64 platforms, doorbells update from guest VM may not be seen
on SPDK target side. This is because there is memory type mismatch
situation here. That is on guest VM side, the doorbells are treated as
device memory while on SPDK target side, it is treated as normal
memory. And this situation cause problem on ARM platform.
Refer to "https://developer.arm.com/documentation/102376/0100/
Memory-aliasing-and-mismatched-memory-types". Only using spdk_mb()
cannot fix this. Use "dc civac" to invalidate cache may solve this.

Profiling data did not show big performance degradataion.

vfio-user has this issue.  While here, we add one more thread poll
to avoid such issue.

0a3383eec2 nvmf/vfio-user: fix race condition when free_ctrlr()
This commit fixes a race condition when calling free_ctrlr(),
nvmf_vfio_user_close_qpair->free_qp will set controller `ctrlr->qp[qid] = NULL`
finally, when calling free_ctrlr() we also need to check `ctrlr->qp[qid]`
is NULL or not, when there are multiple IO queues, we need a lock to protect
`ctrlr->qp[qid]`.  However, the call to free_qp() in free_ctrlr() is valid
only when killing SPDK target, for all other cases, e.g: VM disconnected,
the queue pairs are already freed, so here we can process these different
cases separately, and avoid extra lock.

stop the submission path and leave a TODO comment here until
we have an asynchronous way to do this.

Also use the `<=` for the boundary check.

82fb2615c7 nvmf/vfio-user: fix SQ race condition
The host driver should do a wmb() before it updates the SQ tail doorbell
to ensure that any writes to the SQ are guaranteed to be visible if a
doorbell update is visible (a store-release) - and indeed, this is what
the Linux NVMe driver does.

Therefore, we require a rmb() after we read the tail doorbell in order
to synchronise properly with the host driver (we need a load-acquire),
and guarantee that the updates to the SQ are visisble to us.
