If a device without a driver is recovered via EEH, the flag EEH_DEV_NO_HANDLER is incorrectly left set on the device after recovery, because the test in eeh_report_resume() for the existence of a bound driver is done before the flag is cleared. If a driver is later bound, and EEH experienced again, some of the drivers EEH handers are not called.
To correct this, clear the flag unconditionally after EEH processing is complete.
