leds: max77650: Add of_node_put() before return

Browse source

Each iteration of for_each_child_of_node puts the previous node, but in
the case of a return from the middle of the loop, there is no put, thus
causing a memory leak.
Hence create a new label, err_node_put, which puts the previous node and
returns variable rv. Modify the mid-loop return statements to instead
store the return value in rv and jump to err_node_put.
Issue found with Coccinelle.
