Refactoring done in commit
(46ee04 IEEE 802.11u: Allow Interworking and HESSID to be configured)
broke adding extra ies in sched scan. The ies stopped being added
to the scan params within wpa_supplicant_extra_ies but no code
was added to add them in wpa_supplicant_req_sched_scan.
Fix it and remove unused params arg in wpa_supplicant_extra_ies.
