I did this just because I refactored the vhost_user init code, making
the char dev handler to initiate all ncs. Hence I turned net_vhost_link_down()
to handle all ncs, just like what I did for vhost_user_start().
And TBH, I'm not aware of qmp_set_link() before, and after reading the
code, I do think we can simply invoke it instead. And thanks for the
info.

Thanks for the review. May I add your reviewed-by if I fix above issue?
