mac80211: remove some unused code
There are a number of unused variables that gcc pointed out (when building with W=1) as well as some conditions that can never be true due to the datatypes used: unsigned values can't be less than zero. Remove this code. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
