glusterd: handling brick termination in brick-mux
Problem: There's a race between the glusterfs_handle_terminate()
response sent to glusterd from last brick of the process and the
socket disconnect event that encounters after the brick process
got killed.
Solution: When it is a last brick for the brick process, instead of
sending GLUSTERD_BRICK_TERMINATE to brick process, glusterd will
kill the process (same as we do it in case of non brick multiplecing).
The test case is added for https://bugzilla.redhat.com/show_bug.cgi?id=1549996
