KVM: MMU: protect kvm_mmu_change_mmu_pages with mmu_lock

(cherry picked from commit 7c8a83b75a38a807d37f5a4398eca2a42c8cf513)

kvm_handle_hva, called by MMU notifiers, manipulates mmu data only with
the protection of mmu_lock.

Update kvm_mmu_change_mmu_pages callers to take mmu_lock, thus protecting
against kvm_handle_hva.
