iwlagn: fix warning when set WEP key
iwl_clear_station_table will be called every time rxon called. In this function ucode_key_table is set to 0 even though a static WEP security is set. This will cause in many warning and might be an issue if dynamic WEP is set. This patch make sure we keep track of all existing static WEP when this function is called.
