iwlwifi: assure we complete scan in scan_abort and scan_check works

Assure we complete scan in mac80211 when we abort scanning (scan_abort
work) or scan timeout occurs (scan_check work). Currently
iwl_scan_cancel_timeout() procedure force scan finish in mac80211
at the end of timeout loop, so we can use it in proper work functions.
