phy: rockchip: inno-usb2: Fix a double free bug in rockchip_usb2phy_probe()

[ Upstream commit e07dea3de508cd6950c937cec42de7603190e1ca ]

The for_each_available_child_of_node() calls of_node_put() to
release child_np in each success loop. After breaking from the
loop with the child_np has been released, the code will jump to
the put_child label and will call the of_node_put() again if the
devm_request_threaded_irq() fails. These cause a double free bug.

Fix by returning directly to avoid the duplicate of_node_put().
