afr: replica pair going offline does not require CHILD_MODIFIED event
As a part of CHILD_MODIFIED event DHT forgets the current layout and
performs fresh lookup. However this is not required when a replica pair
goes offline as the xattrs can be read from other replica pairs. Hence
setting different event to handle replica pair going down.
