fbcon: Introduce wrapper for console->fb_info lookup
Half of it is protected by console_lock, but the other half is a lot
more awkward: Registration/deregistration of fbdev are serialized, but
we don't really clear out anything in con2fb_map and so there's
potential for use-after free mixups.
First step is to encapsulate the lookup.
