The I/O splitting tests don't pass the I/Os through the normal
completion path, so we need to free the children ourselves.
Fixes all Valgrind warnings for nvme_ns_cmd_ut.

nvme_ut is testing multi-threaded operations, and Valgrind's thread
behavior is different than running the program natively. Under
Valgrind, the unit test essentially hangs waiting for the global
variable to be updated.

nvme_alloc_request() does not zero out the request (this is
intentional, since the real implementation uses a mempool where requests
get reused). Add nvme_allocate_request() wrapper that initializes the
request correctly. This fixes all uses of uninitialized memory caught
by Valgrind in nvme_qpair_ut. This test was also failing in practice on
FreeBSD due to non-zero buffers returned from malloc().

Instead of repeating the check for conditions that must be fulfilled to
continue the tests, just use CU_ASSERT_FATAL, which will abort the test
and return.

The current implementation of nvme_assert in the unit test nvme_impl.h
just prints the message and continues.
We should not be triggering assert conditions, even in the unit test
code, so make nvme_assert actually call assert(). This lets us catch
mistakes in the unit tests more easily.
Also fix the two unit tests that currently trigger an assert:
- The I/O splitting test in nvme_ns_cmd_ut was passing an invalid
combination of NULL payload with non-zero lba_count.
- The ctrlr_cmd test was passing an invalid number of entries to
nvme_ctrlr_cmd_get_error_page(). This case should probably not be an
assert but rather an error code. However, the function does not
return a status code currently, so it is not trivial to make that
change. For now, just drop the asserting test case and the code added
to the test to work around it.
While we're here, fix the macros in the unit test nvme_impl.h so they
are usable in single-line conditionals without braces - that is the
whole point of the do { ... } while (0) pattern, so there should be no
trailing semicolon.

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.
