net: dsa: sja1105: Add of_node_put() before return

Fix following coccicheck warning:
./drivers/net/dsa/sja1105/sja1105_main.c:1193:1-33: WARNING: Function
for_each_available_child_of_node should have of_node_put() before return.

Early exits from for_each_available_child_of_node should decrement the
node reference counter.
