[SCSI] qla2xxx: T10 DIF - Fix incorrect error reporting.
This fix:
- Disables app tag peeking; correct tag check will be added when the
SCSI API is available.
- Always derive ref_tag from scsi_get_lba()
- Removes incorrect swap of FCP_LUN in FCP_CMND
- Moves app-tag error check before ref-tag check. The reason being,
currently there is no interface in SCSI to retrieve the app-tag
for protection I/Os, so driver puts zero for app-tag in the
firmware interface, but requests not to validate it, but when a
ref-tag error is detected by firmware, it would put
expected/actual tags for all the protection tags (guard/app/ref).
As driver checks for app tag error first, a ref-tag error is
incorrectly flagged as app-tag error.
- Convert HBA specific checks to capability based.
