mac80211: determine completed scan type by defined ops
In some cases, determining the completed scan type was
done by testing the SCAN_HW_SCANNING flag.
However, this doesn't take care for the case in which
the hw scan was requested, but hasn't started yet (e.g.
due to active remain_on_channel).
Replace this test by checking whether ops->hw_scan is
defined.
This solves the following warning:
