[PATCH iwl-next v2 07/14] idpf: remove 'vport_params_reqd' field

[Larysa Zaremba]

From: Pavan Kumar Linga <pavan.kumar.linga@xxxxxxxxx>

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.
