P33M a56279ae15 dwc_otg: fix locking around dequeueing and killing URBs ...

kill_urbs_in_qh_list() is practically only ever called with the fiq lock
already held, so don't spinlock twice in the case where we need to cancel
an isochronous transfer.

Also fix up a case where the global interrupt register could be read with
the fiq lock not held.

Fixes the deadlock seen in https://github.com/raspberrypi/linux/issues/2907
