The struct ath_hw member intr_txqs is never reset/assigned outside of ath9k_hw_init_queues() and with the used bitwise-or in the interrupt handling ar9002_hw_get_isr() accumulates all ever set interrupt flags. Fix this by using a pure assign instead of bitwise-or for the first line (note: intr_txqs is only evaluated in case ATH9K_INT_TX bit is set).
