net: phy: Restore phy_resume() locking assumption
commit f5e64032a799 ("net: phy: fix resume handling") changes the
locking semantics for phy_resume() such that the caller now needs to
hold the phy mutex. Not all call sites were adopted to this new
semantic, resulting in warnings from the added
WARN_ON(!mutex_is_locked(&phydev->lock)). Rather than change the
semantics, add a __phy_resume() and restore the old behavior of
phy_resume().
