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.

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.

This will rmmod nvme on Linux, and use the DPDK nic_uio driver
to unbind nvme devices from the nvme driver on FreeBSD.
"nic_uio" is actually a misnomer - it is not NIC driver specific,
and can safely be used to bind NVMe devices to an effectively
null driver.

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.
