Subject: [RFC 08/18] ath9k_hw: check for asynchronous MCI interrupt pending

From: Mohammed Shafi Shajakhan <[email protected]>

MCI interrupt is an asynchronous one, so take care of it by having a
check in ath9k_hw_intrpend, which actually decides whether the interrupt
is really for the driver from ath_isr
