libata: ATA_12/16 doesn't fall into ATAPI_MISC
SAT passthrus don't really fit into ATAPI_MISC class. SAT passthru
commands always transfer multiple of 512 bytes and variable length
response is not allowed. This patch creates a separate category -
ATAPI_PASS_THRU - for these.
This fixes HSM violation on "hdparm -I".
