James Bergsten 8785d5052d nvme: spdk_nvme_ctrlr_alloc_io_qpair extensions 
Adds fields to structure spdk_nvme_io_qpair_opts.

These fields allow specifying the locations of memory buffers used
for the submission and/or completion queues.

By default, vaddr is set to NULL meaning SPDK will allocate the memory to be used.

If vaddr is NULL then paddr must be set to 0.

If vaddr is non-NULL, and paddr is zero, SPDK derives the physical
address for the NVMe device, in this case the memory must be registered.

If a paddr value is non-zero, SPDK uses the vaddr and paddr as passed.

SPDK assumes that the memory passed is both virtually and physically
contiguous.

If these fields are used, SPDK will NOT impose any restriction
on the number of elements in the queues.

The buffer sizes are in number of bytes, and are used to confirm
that the buffers are large enough to contain the appropriate queue.

These fields are only used by PCIe attached NVMe devices.  They
are presently ignored for other transports.
