Enable WME QoS in IBSS mode by adding a WME information element to beacons and
probe respones and by checking for it and marking stations as WME capable if it
is present.

v3: use GFP_ATOMIC and re-organize nesting of "if" statements. allthough in
practice we would probaby always have the rates element i think it's more
correct to code it like this.
