Subject: [PATCH] clock: Reset state when switching port with same best clock.
When the best port is changed, but the ID of the best clock doesn't
change (e.g. a passive port is activated on link failure), reset the
current delay and other master/link-specific state to avoid the switch
throwing the clock off.
