Description
in SnapIterator in rbd.pyx, rbd_snap_list_end() is called by SnapIterator.__dealloc__(). and rbd_snap_list_end() freessnaps->name if it is not nullptr. but there is chance that snaps->name is never initialized after snaps is allocated by SnapIterator.__init__, in that case, we will free() a wild pointer.
