Since the nvme_tracker struct was extended to allow space for 253 SGL
descriptors at 16 bytes each, we can use the same amount of space in the
other branch of the union to store 506 PRP list entries at 8 bytes each.
This increases the maximum supported I/O size for PRP-only devices from
128 KB to slightly under 2 MB.
