[SCSI] st: convert check_tape to use st_scsi_kern_execute
This replaces st_do_scsi in check_tape (READ_BLOCK_LIMITS and MODE_SENSE) with st_scsi_kern_execute. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Acked-by: Kai Makisara <Kai.Makisara@kolumbus.fi> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
