glusterfsd: Memleak in glusterfsd process while brick mux is on

Problem: At the time of stopping the volume while brick multiplex is
         enabled memory is not cleanup from all server side xlators.

Solution: To cleanup memory for all server side xlators call fini
          in glusterfs_handle_terminate after send GF_EVENT_CLEANUP
          notification to top xlator.
