The actual interface is take_over_console(); the _workaround_ is
exposing do_take_over_console() for fbcon to wrap.

This _workaround_ willn't work, take_over_console will hold console_lock internal,
but do_take_over_console need caller hold console_lock, then we can't rewrite
do_take_over_console as a wrap base on take_over_console.

The workaround I'm referring to is commit 50e244cc793 which
exposed do_take_over_console() as an interface to band aid the lock

I'm ok with take_over_console() being a lock wrapper around
do_take_over_console(), if you are trying to preserve your
other changes.
