[PATCH] phy: core: Fix refcount leak bug in of_phy_provider_lookup()

We should call of_node_put() when breaking out of for_each_child_of_node()
as it will automatically increase and decrease the refcount.

Fixes: 2a4c37016ca9 ("phy: core: Fix of_phy_provider_lookup to return PHY provider for sub node")
