[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.
