Daniel Verkamp 4af4e4f509 nvme: adjust physically contiguous memory comments
The NVMe PCIe transport only requires physically contiguous allocations
for struct nvme_tracker and the I/O SQ and CQ entries, which are already
handled separately.  Change the comments to indicate that struct
nvme_payload's contiguous type only requires the memory to be virtually
contiguous, since nvme_pcie_prp_list_append() already steps through the
buffer and translates each (4K) page independently.
