For P2P mode, the WLAN interface may be requested to remain on a
specific channel and then to send some management frames on that
channel. Now chananel frequency 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 ROC channel frequency.
This change only applies to WCN7850, other chips are not affected.
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
