KVM: x86/mmu: Allow zapping collapsible SPTEs to use MMU read lock

To reduce the impact of disabling dirty logging, change the TDP MMU
function which zaps collapsible SPTEs to run under the MMU read lock.
This way, page faults on zapped SPTEs can proceed in parallel with
kvm_mmu_zap_collapsible_sptes.
