New hardware, old problem: stuck beacon when here is WiFi traffic

[Adrian Chadd]

Well, right now I'm trying to figure out whether there's a race
condition in setting up / enabling the TX queue that I haven't yet
seen before, or whether we've hit another one of those corner case
bugs in the TX queue handling.

I may add in a hack to the completion code that checks if the queue
isn't active and if it isn't (but there's frames in the TX queue), it
restarts TX.
