atomic.h: i386 type safety fix

Remove an explicit cast to an integer type for the result returned by cmpxchg.
 It is not per se a problem on the i386 architecture, because sizeof(int) ==
sizeof(long), but whenever this code is cut'n'pasted to a accept passing an
atomic64_t value as parameter to cmpxchg, xchg and add_unless, having 64 bits
inputs casted to 32 bits.
