iwlagn: fix channel switch locking
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.
