Subject: [PATCH] spi: orion: Add of_node_put() before goto

Fix following coccicheck warning:
./drivers/spi/spi-orion.c:738:1-33: WARNING: Function
for_each_available_child_of_node should have of_node_put() before goto

Early exits from for_each_available_child_of_node should decrement the
node reference counter.
