Specifically, at the start of pmap_enter_quick_locked(), we would sometimes have a TLB entry for an invalid PTE, and we would need to issue a TLB invalidation before exiting pmap_enter_quick_locked(). However, we should never have a TLB entry for an invalid PTE. r349905 has addressed the root cause of the problem, and so we no longer need this workaround. X-MFC after: r349905 END
