mount/fuse: cleanup old graphs.
After a graph switch, a PARENT_DOWN event from fuse indicates protocol/client to shutdown all its sockets. However, this event will be sent only when the first fop is received from fuse mount after graph switch. Also, this event is sent only on previously active graph. So, if there are multiple graph switches when there is no activity on mountpoint, we'll be left with a list of graphs with their sockets still open. This patch fixes the issue by sending PARENT_DOWN to previously non-active graph when a new graph is available irrespective of whether there is an activity on mount-point.
