net: phy: Ensure state transitions are processed from phy_stop()

Browse source

[ Upstream commit 4203d84032 ]

In the phy_disconnect() -> phy_stop() path, we will be forcibly setting
the PHY state machine to PHY_HALTED. This invalidates the old_state !=
phydev->state condition in phy_state_machine() such that we will neither
display the state change for debugging, nor will we invoke the
link_change_notify() callback.

Factor the code by introducing phy_process_state_change(), and ensure
that we process the state change from phy_stop() as well.
