ath9k: reset after PCI FATAL/PERR interrupts
ath9k_hw_getisr() doesn't appear to set anything in the status mask for PCI FATAL or PERR interrupts (AR_INTR_SYNC_HOST1_FATAL/PERR), which the open-source HAL seems to do. This means that the card isn't reset after these interrupts. This patch seems to fix a problem where the wireless drops out with an "ath9k: received PCI FATAL interrupt" in dmesg after some time; the hardware is an AR5416 in an ASUS WL-500W running 2.6.28.7 (OpenWRT) and compat-wireless 2009-03-31.
