mm: Disable lock elision for zap pte range zap pte range tends to exceed the transaction capacity, while walking the page tables under lock. Since the lock is all shared with other VM paths, this is a tough situation to handle for the automatic adaptation, while relies on per lock state. So disable elision for it explicitly.
