Fix m32r __xchg

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.
