x86: cast cmpxchg and cmpxchg_local result for 386 and 486

mm/slub.c: In function 'slab_alloc':
mm/slub.c:1637: warning: assignment makes pointer from integer without a cast

A cast is needed in the 386 and 486 code because the type is a pointer.  In
every other integer case the original cmpxchg code (and the cmpxchg_local
which has been copied from it) worked fine, but since we touch a pointer,
the type needs to be casted in the cmpxchg_local and cmpxchg macros.

The more recent code (586+) does not have this problem (the cast is already
there).
