[PATCH] phy: hisilicon: add missing call to of_node_put()

[Yang Li]

In one of the error paths of the for_each_child_of_node() loop,
add missing call to of_node_put().

Fix the 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 around
line 158.
