The function ide_cd_queue_pc should be checked as the bufflen arg is
dereferenced and lots of callers are passing in NULL.

Make a redundant copy of the packet command bits into rq->cmd. Later, after
all drivers have been converted, it'll be switched to use that in the
common code instead of pc->c. While at it, simplify ide_tape_create_rw_cmd.

ide-tape uses rq->cmd for special commands from the chrdev interface so move
those to byte 13 (BLK_MAX_CDB = 16) since a packet cmd is max 12 bytes.

The if-else block in the IRQ handler is only temporary so that bisect searches

It is important that drive->pc_callback is set prior to enabling IRQs on the
device since this is called from the IRQ handler. Otherwise it hurts as I learnt
the hard way from the several "Kernel panic - not synching: Fatal exception in
interrupt" during the weekend :).
