So far we relied on .put_super = binderfs_put_super() to destroy info we stashed in sb->s_fs_info. This gave us the required ordering between ->evict_inode() and sb->s_fs_info destruction. But the current implementation of binderfs_fill_super() has a memory leak in the rare circumstance that d_make_root() fails because ->put_super() is only called when sb->s_root is initialized. Fix this by removing ->put_super() and simply do all that work in binderfs_kill_super().
