Connection problems with wme enabled

[Sam Leffler]

Actually, I take it back.  WME did get enabled for all drivers by 
default now and I'll look to switch that back.  What I was thinking of 
was that I fixed an issue with ath where WME+TKIP did not work and 
because of that enabled WME use for all ath parts.

It would still be worth understanding why WME operation breaks iwi; 
please provide logs showing what is happening.
