loop: deprecate autoloading callback loop_probe() 



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 fbdee71b ("block: deprecate autoloading based on dev_t").
