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.

84cfc97fdf nvme: fix allocation in test_nvme_qpair_destroy
act_tr is supposed to be allocated with the system allocator
(malloc/calloc) rather than nvme_malloc.

Additionally, the size was incorrect - act_tr is an array of pointers,
not a single struct nvme_tracker.

Remove unnecessary allocation (which was missing the corresponding free
call).

Simplify code to avoid unnecessary ret_val variable.

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.

a6cf458c9d nvme: tweak unit test PCI config space accessors
Make nvme_pcicfg_read32 set the referenced variable and make
nvme_pcicfg_write32 appear to read it so that the compiler doesn't warn
about unused/uninitialized data.

7f9d22a494 nvme: clean up nvme_ctrlr_cmd_ut
Replace a bunch of allocations with stack variables.

Remove many unnecessary variables.

The actual tests are unchanged (and still not testing very much), but
this removes a lot of cruft that should make it easier to see what the
tests are actually doing.
