    iwlwifi: don't throw error when trying to remove IGTK · 197288d5
    Luca Coelho authored
    The IGTK keys are only removed by mac80211 after it has already
    removed the AP station.  This causes the driver to throw an error
    because mac80211 is trying to remove the IGTK when the station doesn't
    exist anymore.
    
    The firmware is aware that the station has been removed and can deal
    with it the next time we try to add an IGTK for a station, so we
    shouldn't try to remove the key if the station ID is
    IWL_MVM_INVALID_STA.  Do this by removing the check for mvm_sta before
    calling iwl_mvm_send_sta_igtk() and check return from that function
    gracefully if the station ID is invalid.
