Subject: [PATCH 563/566] posix: brick process crash after stop the volume
 while brick mux is on

Problem: sometime brick process is getting crash after stop the volume
         while brick mux is enabled and no. of volumes are high

Solution: In posix notify at the time close mount_lock dir , dir handle
          needs to set NULL to avoid the reuse of same dir handle.
