scsi: core: Kill DRIVER_SENSE
Replace the check for DRIVER_SENSE with a check for
scsi_status_is_check_condition().
Audit all callsites to ensure the SAM status is set correctly. For
backwards compability move the DRIVER_SENSE definition to sg.h, and update
sg, bsg, and scsi_ioctl to set the DRIVER_SENSE driver_status whenever
SAM_STAT_CHECK_CONDITION is present.
[mkp: fix zeroday srp warning]
