      iwlagn: fix channel switch locking · 6f213ff1
      Stanislaw Gruszka authored
      We use priv->mutex to avoid race conditions between iwl_chswitch_done()
      and iwlagn_mac_channel_switch(), when marking channel switch in
      progress. But iwl_chswitch_done() can be called in atomic context
      from iwl_rx_csa() or with mutex already taken from iwlagn_commit_rxon().
      
      These bugs were introduced by:

          iwlwifi: support channel switch offload in driver
      
      To fix remove mutex from iwl_chswitch_done() and use atomic bitops for
      marking channel switch pending.
      
      Also remove iwl2030_hw_channel_switch() since 2000 series adapters are
      2.4GHz only devices.
