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.
