Phillip LougherandGreg Kroah-Hartman 0b7f6d02d4 squashfs: fix memory leak in squashfs_fill_super ...

commit b64700d41b upstream.

If sb_min_blocksize returns 0, squashfs_fill_super exits without freeing
allocated memory (sb->s_fs_info).

Fix this by moving the call to sb_min_blocksize to before memory is
allocated.
