Wei Yang a1802098ef maple_tree: fix mt_destroy_walk() on root leaf node
commit ea9b77f98d upstream.

On destroy, we should set each node dead.  But current code miss this when
the maple tree has only the root node.

The reason is mt_destroy_walk() leverage mte_destroy_descend() to set node
dead, but this is skipped since the only root node is a leaf.

Fixes this by setting the node dead if it is a leaf.
