> Add support for virtchnl_vector_map.[rxq|txq]_map to use bitmap to
> associate indicated queues with the specified vector. This support is needed
> since the Windows AVF driver calls VIRTCHNL_OP_CONFIG_IRQ_MAP for
> each vector and used the bitmap to indicate the associated queues.
> 
> Updated ice_vc_dis_qs_msg to not subtract one from
> virtchnl_irq_map_info.num_vectors, and changed the VSI vector index to
> the vector id. This change supports the Windows AVF driver which maps one
> vector at a time and sets num_vectors to one. Using vectors_id to index the
> vector array .
> 
> Add check for vector_id zero, and return VIRTCHNL_STATUS_ERR_PARAM if
> vector_id is zero and there are rings associated with that vector.
> Vector_id zero is for the OICR.
