glusterd: clean up portmap on brick disconnect
GlusterD's portmap entry for a brick is cleaned up when a PMAP_SIGNOUT event is initiated by the brick process at the shutdown. But if the brick process crashes or gets killed through SIGKILL then this event is not initiated and glusterd ends up with a stale port. Since GlusterD's portmap traversal happens both ways, forward for allocation and backward for registry search, there is a possibility that glusterd might end up running with a stale port for a brick which eventually will end up with clients to fail to connect to the bricks. Solution is to clean up the port entry in case the process is down as part of the brick disconnect event. Although with this the handling PMAP_SIGNOUT event becomes redundant in most of the cases, but this is the safeguard method to avoid glusterd getting into the stale port issues.
