athk6l: Fix channel list processing in scan requests

Limit the length of the channel list to WMI_MAX_CHANNELS to avoid
rejection of the request in wmi.c. Since there is not really much
point in using a specific list of more than 32 channels, drop the
channel list if more channels are specified and scan all channels.

Fix cfg80211 scan API use: ar->scan_req must be set only if returning
success from scan() handler. The previous version would result in use
of freed memory and likely kernel panic should the scan request fail
to be sent to the target.

iwlagn: move the check_empty logic to the transport layer

This logic is responsible to tell mac80211 when the HW queues are
empty and the BA session can be started / torn down.

Fix a bug on the way:
When the the Tx BA session is stopped and the HW queues aren't empty,
we stop the SW queue to drain the HW queue and then switch to the
legacy HW queue. This is the IWL_EMPTYING_HW_QUEUE_DELBA state.

While in this state, we never wake the SW queue, even when the HW
queue is almost empty, since we need to drain it completely. Look
at iwl_trans_pcie_reclaim regarding this.

Once the HW queue is really empty, we must wake the SW queue in order
to get traffic to the legacy queue.
This step was missing leading to an odd situation were the traffic
would just stall after we tore down a Tx BA session while the HW
queue was not empty.
