This passes in the block_group and the free_space_ctl, but we can get this from the block group itself. Part of this is because we call it from __load_free_space_cache, which can be called for the inode cache as well. Move that call into the block group specific load section, wrap it in the right lock that we need for the assertion (but otherwise this is safe without the lock because this happens in single-thread context). Fix up the arguments to only take the block group. Add a lockdep_assert as well for good measure to make sure we don't mess up the locking again.
