qcacmn: Update scan_ctrl_flags when strict passive scan enabled

Analysis: strict passive scan is not working as the scan_ctrl_flags
check is missed when strict passive scan enabled

Change-Details : Added a support in ol_ath_scan_start_send() and
send_scan_start_cmd_non_tlv() to update the scan_ctrl_flags with
WMI_SCAN_FLAG_STRICT_PASSIVE_ON_PCHN when strict_pscan_enabled
