KVM/MMU: Add tlb flush with range helper function

Browse source

This patch is to add wrapper functions for tlb_remote_flush_with_range
callback and flush tlb directly in kvm_mmu_zap_collapsible_spte().
kvm_mmu_zap_collapsible_spte() returns flush request to the
slot_handle_leaf() and the latter does flush on demand. When
range flush is available, make kvm_mmu_zap_collapsible_spte()
to flush tlb with range directly to avoid returning range back
to slot_handle_leaf().
