ide: add ide_execute_pkt_cmd() helper
Add ide_execute_pkt_cmd() helper for executing PACKET command, then convert ATAPI device drivers to use it. As a nice side-effect this fixes ide-{floppy,tape,scsi} w.r.t. ide_lock taking (ide-cd was OK). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
