KVM: x86/mmu: Split kvm_mmu_zap_all_fast() into "front" and "back" halves

Split kvm_mmu_zap_all_fast() into a "front half" and a "back half", where
the front half is everything that runs with mmu_lock held for write, and
the back half is the code that runs outside of mmu_lock.  This will allow
putting more code inside kvm_arch_flush_shadow_memslot()'s critical section
without having to take mmu_lock twice in quick succession.

No functional change intended.
