fb: rework locking to fix lock ordering on takeover
commit 50e244cc793d511b86adea24972f3a7264cae114 upstream.
Adjust the console layer to allow a take over call where the caller
already holds the locks. Make the fb layer lock in order.
This is partly a band aid, the fb layer is terminally confused about the
locking rules it uses for its notifiers it seems.
