Subject: [PATCH] net: phy: add missing of_node_put before return

From: Wang Qing <wangqing@...o.com>

Fix following coccicheck warning:
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.
