iwlwifi: do not force complete scan too early
Currently we force scan complete at the end of iwl_scan_cancel_timeout
function. This cause race condition when we can get a new scan request
from mac80211 and complete it by iwl_bg_complete from older scan. Change
code to force scan complete only when really needed: device goes down,
interface is removed or scan timeout occurs.
