[PATCH net-next v7 06/15] idpf: remove 'vport_params_reqd' field

From: Pavan Kumar Linga <[email protected]>

While sending a create vport message to the device control plane, a create
vport virtchnl message is prepared with all the required info to initialize
the vport. This info is stored in the adapter struct but never used
thereafter. So, remove the said field.
