qcacld-3.0: Handle SAP+NAN concurrency when NAN_DBS isn't supported

When nan_sap and nan_disable are supported but nan_dbs is not
supported,
1. Allow SAP+NAN concurrency if force SCC is supported
2. Disable NAN if SAP comes up on a different band and force SCC is
   not supported
3. Reject NAN enable if SAP is already on a different band and force SCC is
   not supported
