For macro for_each_child_of_node(parent, child), refcount of @child has
been increased before entering its loop body, so normally needs to call
of_node_put(@child) before returning from the loop body to avoid refcount
leakage.
of_phy_provider_lookup() has such usage but does not call of_node_put()
before returning, so cause leakage of the OF node refcount.
Fix by simply calling of_node_put() before returning from the loop body.
The APIs affected by this issue are shown below since they indirectly
invoke problematic of_phy_provider_lookup().
phy_get()
of_phy_get()
devm_phy_get()
devm_of_phy_get()
devm_of_phy_get_by_index()
