wireless: fix warnings from QoS patch
Browse files Browse the repository at this point in the history
When I removed the special "default" meaning from the QoS
parameters, I forgot to update drivers and this lead to
warnings because some drivers were checking for the special
values and putting in defaults. This fixes that by removing
the default special-casing completely.
