iwlwifi: cancel scan when down the device

Browse source 
Always cancel scan when stooping device and scan is currently pending,

abort_scan to different workqueue than priv->workqueue.

Patch fix not cancel scanning when restarting firmware, what is
one of the causes of wdev_cleanup_work warning (together with permanent
network connection lost) reported at
