RCA :

The mdcache entry created during the export of gluster volume is not cleaned up
properly during unexport. So when the export is again added, it gives a entry
already exist error(with respect to fsal_gluster, glfs_object corresponding to
this entry is invalid) and further operation on this entry result in a
crash(like mounting)

On further dig up it seems to be refcount of this variable never become zero
during unexport, therefore the entry is not removed from mdcache layer.

For version 2.3 these entries were cleanup properly during
.
Similar problem is also present in fsal_vfs, but it didn't result any crash.
