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?

Pretty sure EEH will only process a single error at a time so this
*should* always let you infer from context, but PHB and PE should
probably be included anyway.  It'd be cool to move pe_{err/warn/info}()
out of powernv for messages like this.
