[PATCH] mm: fix misuse of update_mmu_cache() in do_anonymous_page()

[Qi Zheng]

As message in commit 7df676974359 ("mm/memory.c: Update local TLB
if PTE entry exists") said, we should update local TLB only on the
second thread. So fix the misuse of update_mmu_cache() by using
update_mmu_tlb() in the do_anonymous_page().
