i2c: mux: demux-pinctrl: fix OF node leak on kstrdup failure

Browse source

of_parse_phandle() takes a reference on the parent node. If a later
devm_kstrdup() fails, err_rollback only releases nodes for indices
0..i-1, so the current node is leaked.

of_node_put() the current parent before rolling back.
