hw/nvme: add new command abort case

NVMe command set specification for end-to-end data protection formatted
namespace states:

o If the Reference Tag Check bit of the PRCHK field is set to ‘1’ and
the namespace is formatted for Type 3 protection, then the
controller:
▪ should not compare the protection Information Reference Tag
field to the computed reference tag; and
▪ may ignore the ILBRT and EILBRT fields. If a command is
aborted as a result of the Reference Tag Check bit of the
PRCHK field being set to ‘1’, then that command should be
aborted with a status code of Invalid Protection Information,
but may be aborted with a status code of Invalid Field in
Command.

Currently qemu compares reftag in the nvme_dif_prchk function whenever
Reference Tag Check bit is set in the command. For type 3 namespaces
however, caller of nvme_dif_prchk - nvme_dif_check does not increment
reftag for each subsequent logical block. That way commands incorporating
more than one logical block for type 3 formatted namespaces with reftag
check bit set, always fail with End-to-end Reference Tag Check Error.
Comply with spec by handling case of set Reference Tag Check
bit in the type 3 formatted namespace.

hw/nvme: 64-bit pi support

This adds support for one possible new protection information format
introduced in TP4068 (and integrated in NVMe 2.0): the 64-bit CRC guard
and 48-bit reference tag. This version does not support storage tags.

Like the CRC16 support already present, this uses a software
implementation of CRC64 (so it is naturally pretty slow). But its good
enough for verification purposes.

This may go nicely hand-in-hand with the support that Keith submitted
for the Linux kernel[1].
