Invoke futex wait with correct value If we were woken up early, Mutex::ExclusiveLock() would mistakenly retry the wait with the original state_and_contenders value, in spite of the fact that the contenders part might have changed. This could turn a mutex wait loop into a spin loop, causing a battery issue, and an occasional livelock issue. Fix that oversight.
