Add a single log line at the end of successful EEH recovery, so that
it's clear that event processing has finished.

Is it possible for recovery for multiple devices to be interleaved?

Should that message include the device?

No, all the calls are serialized. They're only called from
eeh_event_handler() which is in the main loop of a kernel thread (see
eeh_event_init()).
