mac80211: remove ieee80211_key_removed
This API call was intended to be used by drivers if they want to optimize key handling by removing one key when another is added. Remove it since no driver is using it. If needed, it can always be added back. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
