[PATCH] radix_tree_delete API improvement
radix_tree_delete() currently returns 0 on success, -ENOENT if there was
nothing to delete.
But it is more useful to return the address of the deleted item on success
and NULL if there was no matching item. It can potentially save a
lookup+delete operation.
