Natalia Petrova 21bc51e29e net: qrtr: free memory on error path in radix_tree_insert()
commit 29de68c2b3 upstream.

Function radix_tree_insert() returns errors if the node hasn't
been initialized and added to the tree.

"kfree(node)" and return value "NULL" of node_get() help
to avoid using unclear node in other calls.
