The existing code was using sizeof() on a calculation that already
returned the right size, so this would originally just memset() 4 bytes
instead of the whole region.
The spec requires the doorbell buffer to be exactly one physical memory
page, and our controller emulation chooses MPS so that only 4096-byte
pages are supported, so just zero out the page and drop the calculation
entirely.

These assert() calls were all checking guest-provided data; it should
not be possible for a guest to trigger an assert(), so replace them with
actual runtime error checks (which won't get removed in release builds).

Now that spdk_vhost_gpa_to_vva() is used in place of
rte_vhost_gpa_to_vva(), we can directly use the void * return value
instead of casting it via uintptr_t.

Moved it to the DPDK thread, so that we don't stress
SPDK I/O reactors on device start/stop. This is mandatory
if we want to maintain hundreds of simultaneous connections.
This patch also fixes various memory registrations leaks
in cases where further device initiation fails.

Due to the check on line 153 in t_nvme_dev, Klocwork
thinks nvme can be null. Therefore, we must check that
it isn't null before dereferencing it. We can either
solve this the way I have here, or remove check
that causes to_nvme_dev to return null.

Similar with exist vhost scsi/blk target, this commit introduces
a new target: vhost nvme I/O slave target, QEMU will present an
emulated NVMe controller to VM, the SPDK I/O slave target will
process the I/Os sent from Guest VM.
Users can follow the example configuation file to evaluate this
feature, refer to etc/spdk/vhost.conf.in [VhostNvme].
