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.

The Linux pagemap-based implementation obviously does not
work on FreeBSD. DPDK has data structures describing the huge
pages it has allocated, so use that instead when we need to
populate new 2MB mappings in our tables.

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.

No change in behavior, just a simplification.
We already have a check for retry, so pull the cb_fn check out and put
it under the !retry branch.
This makes it clearer that requests that are going to be retried will
not get their callbacks called.

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.
