Johannes Berg 095d81cee7 mac80211: disable WMM with invalid parameters 
Some APs (notably a Sitecom WL-153 v1 with firmware 1.45) are sending
invalid WMM parameters setting AIFSN, ECWmin and ECWmax to zero. The
spec mandates that the value of AIFSN is at least 2, and some cards
(e.g. Intel with the iwldvm driver) can't transmit when the invalid
QoS parameters are actually uploaded to the firmware.

Since there's little chance of being able to guess the values that
the AP actually meant, disable WMM if such an invalid case is found.
Since ECWmin/ECWmax are allowed to be zero, only verify AIFSN >= 2
and ECWmin <= ECWmax.
