KVM: x86: hyperv: optimize sparse VP set processing
Rewrite kvm_hv_flush_tlb()/send_ipi_vcpus_mask() making them cleaner and
somewhat more optimal.
hv_vcpu_in_sparse_set() is converted to sparse_set_to_vcpu_mask()
which copies sparse banks u64-at-a-time and then, depending on the
num_mismatched_vp_indexes value, returns immediately or does
vp index to vcpu index conversion by walking all vCPUs.
To support the change and make kvm_hv_send_ipi() look similar to
kvm_hv_flush_tlb() send_ipi_vcpus_mask() is introduced.
