In case of Passpoint, the WLAN interface may be requested to remain on a specific channel and then to send some management frames on that channel. Now chanfreq of wmi_mgmt_send_cmd is set as 0, as a result firmware may choose a default but wrong channel. Fix it by assigning chanfreq field with the designated channel. This change only applies to WCN6855 and QCA6390, other chips are not affected.
