8d424e6e71 nvme: simplify logic for whether to call callback
No change in behavior, just a simplification.

We already have a check for retry, so pull the cb_fn check out and put
it under the !retry branch.

This makes it clearer that requests that are going to be retried will
not get their callbacks called.

3181a61450 nvme: replace stray printf with nvme_printf
This is the only place that was using printf directly in the NVMe
library.  Replace it with the official nvme_printf logging mechanism.

5717784633 nvme: assert that tracker's request is valid
In nvme_qpair_complete_tracker, make sure we got a valid request in the
tracker that is being completed.

This should never occur in practice, but safeguard against it in case of
programmer error.  Fixes a scan-build warning about potential NULL
dereference.

c028633b50 nvme: assert valid nvme_qpair_construct parameters
Document the assumptions made by qpair_construct using asserts.

These values can't actually be 0 in practice due to the way they are
derived, but scan-build can't see that.  It is also useful to have these
asserts in case of future modifications.

8217814218 nvme: remove dump_command and dump_completion
nvme_dump_command is totally unused aside from the unit test.

nvme_dump_completion was used in qpair, but it can be replaced with the
equivalent nvme_qpair_print_completion.

Also added the missing nvme_completion fields to nvme_qpair_print_completion
that had been printed by nvme_dump_command.
