ACPICA: events/evxfregn: don't release the ContextMutex that was never acquired

Browse Source 
This bug was first introduced in c27f3d011b, where the author of the
patch probably meant to do DeleteMutex instead of ReleaseMutex. The
mutex leak was noticed later on and fixed in e4dfe10837, but the bogus
MutexRelease line was never removed, so do it now.
