Since netpoll is best-effort, we can elide that I think.
The more requirements you put into this ->poll_controller()
handler, the more complicated it gets.

Furthermore, this should work out.  If the link is down, the top level
poll loop will timeout waiting for the TX queue to open up, which will
kick the netpoll processing into a work queue, the link handling will
be allowed to occur meanwhile.
