hw/nvme: use prinfo directly in nvme_check_prinfo and nvme_dif_check
The nvme_check_prinfo() and nvme_dif_check() functions operate on the
16 bit "control" member of the NvmeCmd. These functions do not otherwise
operate on an NvmeCmd or an NvmeRequest, so change them to expect the
actual 4 bit PRINFO field and add constants that work on this field as
well.
