[PATCH] phy: hisilicon: Add of_node_put() in phy-hisi-inno-usb2

Fix following coccicheck warning:
./drivers/phy/hisilicon/phy-hisi-inno-usb2.c:138:1-23: WARNING: Function
for_each_child_of_node should have of_node_put() before break

Early exits from for_each_child_of_node should decrement the
node reference counter.
