When trying to create a scsi dev with inexistent
lun (bdev name), the scsi_dev_construct would
just return a NULL without printing any error.
We should probably return an error code of some
kind, but for now let's just print an extra
message.

Instead of inserting a task into the TAILQ and then
immediately taking it back off, just pass the task
to bdevperf_submit_single instead.
This reduces overhead of bdevperf compared to nvme/perf.
nvme/perf does not use a TAILQ at all, and does something
similar by passing the just completed task so it can be
reused by its submit function.

For a given hardware queue size, only allow a quarter of the queue size
to be returned as completions in a single call to
spdk_nvme_qpair_process_completions(), and adjust num_trackers to match
so that num_trackers + max_completions_cap doesn't exceed the hardware
completion queue size. This ensures that there is room in the
completion queue if new I/O is issued in response to completions before
we ring the completion queue doorbell.
The choice of 1/4 queue size is arbitrary; this seems to be a good
compromise between completion batch size and number of trackers.

The normal execution path for read/write commands is that none of the
checks fail; annotate all of the checks in spdk_bdev_scsi_readwrite()
with spdk_unlikely to encourage the compiler to generate the happy path
as straight-line code and move the error handling out of line.

spdk_bdev_scsi_read_write_lba_check() was only called from one spot, and
moving its code directly into the caller makes the code simpler to read
and more consistent, since now all of the sense code setup is directly
in spdk_bdev_scsi_readwrite() rather than being split across two
functions.
No functional change.
