qcacld-3.0: Remove channel parameter check from ndp request

Parameter channel is not a mandatory argument for NDP requerst.
1) Do not fail NDP request if channel parameter is not present.
2) Add channel config parameter in NDP_Initiator_Request, which
   indicates if channel provided is optional, force or not provided
   at all.
