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

[ Upstream commit c53d96a4 ]

This bug was first introduced in c27f3d01, where the author of the
patch probably meant to do DeleteMutex instead of ReleaseMutex. The
mutex leak was noticed later on and fixed in e4dfe108, but the bogus
MutexRelease line was never removed, so do it now.
