ath5k: don't mask off interrupt bits
Since interrupts are already masked by the hardware, there's no need to
discard interrupt bits in the ISR itself. Also, in ath5k_beacon_config
we mask off a couple of bits without locking, so doing this mask in
software can lead to unhandled beacon timer and beacon miss interrupts.
