    ensure we don't use bootconsoles after init has been released
    This is a followup to the cleanups for earlyprintk patch from Gerd Hoffmann
    This ensures that a bootconsole is unregistered if it is not replaced.
    The current implementation spews garbage out the bootconsole in this case,
    since the bootconsole structure is normally in the init section, and is
    freed, but still used.
