iwlagn: avoid sleep in softirq context
__ieee80211_tasklet_handler -> __ieee80211_rx ->
__ieee80211_rx_handle_packet -> ieee80211_invoke_rx_handlers ->
ieee80211_rx_h_decrypt -> ieee80211_crypto_tkip_decrypt ->
ieee80211_tkip_decrypt_data -> iwl4965_mac_update_tkip_key ->
iwl_scan_cancel_timeout -> msleep
Ooops!
Avoid the sleep by changing iwl_scan_cancel_timeout with
iwl_scan_cancel and simply returning on failure if the scan persists.
This will cause hardware decryption to fail and we'll handle a few more
frames with software decryption.
