KVM: arm64: Make active_vmids invalid on vCPU schedule out
Like ASID allocator, we copy the active_vmids into the
reserved_vmids on a rollover. But it's unlikely that
every CPU will have a vCPU as current task and we may
end up unnecessarily reserving the VMID space.
Hence, set active_vmids to an invalid one when scheduling
out a vCPU.
