766afaaacc nvme/test: avoid clang warnings in nvme_ns_cmd_ut
Initialize the full nvme_namespace structure in prepare_for_test() so
that e.g. ns->id is not used uninitialized.

Also check for request allocation failure - if the request is NULL, we
can't run the rest of the tests that dereference request without
crashing.

4ba47234f3 Add pci_device_has_non_null_driver().
This helps enable FreeBSD, where pciaccess pci_device_has_kernel_driver()
is not functional.  The function will return 0 if there is no driver
attached, or the Linux uio or FreeBSD nic_uio driver is attached.  It will
return 1 otherwise.

325b7db392 nvme: use rte_memcpy() to submit commands
GCC generates a series of 64-bit MOV instructions for the memcpy() into
the submission queue.  We can do better with 128-bit SSE2 instructions.

DPDK already has a memcpy implementation that is optimized for small
inline copies, so use it instead of memcpy.

36eea2e1c2 nvme/test: simplify struct zero initializations
Use {} consistently rather than {0} when initializing structs as part of
definitions.

Fixes warnings about initializing subobjects when compiling with clang.

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.

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.

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.
