I can't currently test it the way I was testing before because rt2x00 
currently Oopses on unplug (I'll investigate that tomorrow) but it did 
occasionally crash on scanning even if the interface had been up for a long 
time before and with this patch it has survived quite a few scans.

I'll keep testing but it looks promising.
