Fix crash if LockErrorCleanup() is called twice The refactoring in commit 3c0fd64fec removed the clearing of awaitedLock from LockErrorCleanup(). It's still needed, otherwise LockErrorCleanup() during abort processing will try to update the LOCALLOCK struct even after the lock has already been released. Put it back.
