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.

BUG: 1544090
Signed-off-by: Mohit Agrawal <moagrawa@redhat.com>

Note: Run all test-cases in separate build (https://review.gluster.org/19574)
      with same patch after enable brick mux forcefully, all test cases are
      passed.
