nvme-pci: clear the prp2 field when not used
[ Upstream commit a56ea6147facce4ac1fc38675455f9733d96232b ]
If the prp2 field is not filled in nvme_setup_prp_simple(), the prp2
field is garbage data. According to nvme spec, the prp2 is reserved if
the data transfer does not cross a memory page boundary, so clear it to
zero if it is not used.
