Rajeev Kumar Sirasanagandla cfa662fba6 qcacmn: Fix legacy NDP confirm path 
When NDP v2 support was implemented, event buffer validation check
related to TLV wmi_ndp_channel_info was added. But this check is
breaking legacy NDP confirm path.

To address this, avoid above mentioned check when firmware does not
indicate support for WMI_SERVICE_NDI_DBS_SUPPORT.
