As of commit 6e2d7be8a1 ("vhost: add copy
of virtio headers"), we bundle the appropriate headers that were causing
the Travis-CI build to fail, so re-enable vhost in the Travis build.
This reverts commit 2d0246da83.

This enables the vhost library to build on systems missing the (fairly
recent) linux/virtio_scsi.h header.

Rather than failing silently, let the user know why the listen address
failed.

spdk_nvmf_tgt_listen() can fail due to invalid user input (e.g. from a
config file), so we can't just assert() that it worked.

The previous implementation tried to maintain a ring buffer of completed
I/O retrieved from ->getevents() that had not yet been retrieved by
->event(), but this is not necessary. None of the other FIO engines
implement this sort of ring buffer, and the only code that calls
->getevents() will always retrieve the full number of events via
->event() afterwards.
Instead, just count how many I/Os have been completed within each
->getevents() call in iocq_count, and reset iocq_count on each new
->getevents().

For an NVMe read, send the completion immediately
following the RDMA WRITE, without waiting for
the acknowledgement. RDMA is strictly ordered,
so the WRITE will arrive before the completion.
