s390/atomic,cmpxchg: always inline __xchg/__cmpxchg
Make sure to always inline __xchg() and __cmpxchg() otherwise the
compiler might decide to generate out-of-line versions which will
fail at link time:
s390-linux-ld: lib/atomic64_test.o: in function `__xchg':
>> atomic64_test.c:(.text.unlikely+0xa4): undefined reference to `__xchg_called_with_bad_pointer'
