Subject: [PATCH v3 net-next 2/3] net: phy: ensure phylib state machine is
 stopped after calling phy_stop

The call to the phylib state machine in phy_stop() just ensures that
the state machine isn't re-triggered, but a state machine call may
be scheduled already. So lets's call phy_stop_machine().
This also allows to get rid of the call to phy_stop_machine() in
phy_disconnect().
