ide: cancel pending callbacks on SRST
The SRST implementation did not keep up with the rest of IDE; it is
possible to perform a weak reset on an IDE device to remove the BSY/DRQ
bits, and then issue writes to the control/device registers which can
cause chaos with the state machine.
Fix that by actually performing a real reset.
