- ath9k: do not access hardware on IRQs during reset
-
- Instead of killing interrupts during reset when the first one happens,
- kill them before issuing the reset.
- This fixes an easy to reproduce crash with multiple cards sharing the
- same IRQ.

- ath9k: prevent early IRQs from accessing hardware
-
- IRQs are suppressed if ah == NULL and ATH_OP_INVALID being set in
- common->op_flags. Close a short time window between those two.
