Perhaps, the more that setting the assist is limited to vCPU 0 init.
Which in a way makes sense when considering domain creation, but it
is odd for the case of vCPU 0 being brought down, reset, and then
re-initialized; IOW I think arch_set_info_guest() should further
have constrained the setting by a !d->creation_finished check.
