Summary:	clean up port map on brick disconnect

Fixed In Version:	glusterfs-3.8.4-52.1	Doc Type:	Bug Fix
Doc Text:	The portmap entry allocation that glusterd maintains for each of its brick is cleaned up on a graceful shutdown of the respective brick processes. In case a brick process was killed through SIGKILL signal or crashed, glusterd will not clean up the respective portmap entry allocation and after restarting the same brick glusterd may end up having two portmap allocations for the same brick.glusterd reports with a stale port to the client, resulting failure in connection. With this fix, the stale port entry is removed even for a brick crash or SIGKILL event of a brick process. The client now successfully connects to the brick after the brick is restarted.
