hw/block/nvme: fix create IO SQ/CQ status codes

Replace the Invalid Field in Command with the Invalid PRP Offset status
code in the nvme_create_{cq,sq} functions. Also, allow PRP1 to be
address 0x0.

Also replace the Completion Queue Invalid status code returned in
nvme_create_cq when the the queue identifier is invalid with the Invalid
Queue Identifier. The Completion Queue Invalid status code is
exclusively for indicating that the completion queue identifer given
when creating a submission queue is invalid.

See NVM Express v1.3d, Section 5.3 ("Create I/O Completion Queue
command") and 5.4("Create I/O Submission Queue command").
