loop: deprecate autoloading callback loop_probe()
commit 23881aec85f3219e8462e87c708815ee2cd82358 upstream.
The 'probe' callback in __register_blkdev() is only used under the
CONFIG_BLOCK_LEGACY_AUTOLOAD deprecation guard.
The loop_probe() function is only used for that callback, so guard it
too, accordingly.
See commit fbdee71bb5d8 ("block: deprecate autoloading based on dev_t").
