Two pairs of parenthesis were missing around the result cast of cmpxchg64 and
cmpxchg64_local. This is a rather stupid mistake in
"Cast cmpxchg and cmpxchg_local result for 386 and 486". My bad. This fix
should be folded with the previous.
Sorry for this trivial bug which should have never appeared in the first place.
The aim was to fix cmpxchg and cmpxchg_local, which were used in slub. cmpxchg64
and cmpxchg64_local happen to be only used in LTTng currently.
