Fix m32r __xchg (revised)
the #endif /* CONFIG_SMP */ should cover the default condition, or it may cause
bad parameter to be silently missed.
To make it work correctly, we have to remove the ifdef CONFIG SMP surrounding
__xchg_called_with_bad_pointer declaration. Thanks to Adrian Bunk for
detecting this.
