Remove unused last_scan_full

This parameter was not really used for anything else apart from a debug
message in the same function that set it. In addition, cfg80211 returns
the set of scanned frequencies even for the full scan, so the code that
was setting this conditionally on frequency list not being there was not
really ever entered either.
