net: phy: Avoid deadlock during phy_error()
[ Upstream commit eab127717a6af54401ba534790c793ec143cd1fc ]
phy_error() is called in the PHY state machine workqueue context, and
calls phy_trigger_machine() which does a cancel_delayed_work_sync() of
the workqueue we execute from, causing a deadlock situation.
Augment phy_trigger_machine() machine with a sync boolean indicating
whether we should use cancel_*_sync() or just cancel_*_work().
Fixes: 3c293f4e08b5 ("net: phy: Trigger state machine on state change and not polling.")
