PAGE_SIZE is the host memory page size, which is irrelevant for the NVMe
driver; what we actually care about is the NVMe controller's memory page

behavior is still the same in all cases today, since normal NVMe
controllers report a minimum page size of 4096.

This also changes the SGL -> PRP case to translate each 4K page from
virtual to physical, in case the buffer is not physically contiguous.
