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.
