Subject: hw/block/nvme: fix prp mapping status codes

Address 0 is not an invalid address. Remove those invalikd checks.

Unaligned PRP2 and PRP list entries should result in Invalid PRP Offset
status code and not Invalid Field. Fix that.

See NVMe Express v1.3d, Section 4.3 ("Physical Region Page Entry and
List").
