ide: use IDE_TFLAG_LBA48 for REQ_TYPE_ATA_TASKFILE requests
* Use IDE_TFLAG_LBA48 for REQ_TYPE_ATA_TASKFILE requests in ide_end_drive_cmd() to decide whether we need to read HOB taskfile registers. * Update execute_drive_cmd() accordingly. This is a preparation for the next patch which removes unnecessary writes to HOB taskfile registers for some ATA commands. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
