ath9k_hw_intrpend() is called with ah = NULL from ath_isr(). ath_isr()
checks if SC_OP_INVALID is set, but doesn't check if ah is NULL.
Adding debugging code shows that sc->sc_flags is 0 when it happens.
This must be caused by the recent changes in the initialization.
SC_OP_INVALID should be set in ath_pci_probe() before request_irq().
