x86: replace futex_atomic_cmpxchg_inatomic() with user_atomic_cmpxchg_inatomic
futex_atomic_cmpxchg_inatomic() is simply the 32-bit implementation of
user_atomic_cmpxchg_inatomic(), which in turn is simply a
generalization of the original code in
futex_atomic_cmpxchg_inatomic().
Use the newly generalized user_atomic_cmpxchg_inatomic() as the futex
implementation, too.
[ hpa: retain the inline in futex.h rather than changing it to a macro ]
