drm: extract legacy ctxbitmap flushing
The ctxbitmap code is only used by legacy drivers so lets try to keep it as separated as possible. Furthermore, the locking is non-obvious and kinda weird with ctxlist_mutex *and* struct_mutex. Keeping all ctxbitmap access in one file is much easier to review and makes drm_release() more readable.
