i40e: Communicate VSI id in place of VSI index to the VFs

Browse Source 
This does not affect the Virtual channel API as such but it changes the
meaning of what is communicated to the VSI resource struct as vsi_id.
Earlier vsi_idx was being passed in, which was the index in the PF's VSI
array. Now we pass vsi_id as communicated by the FW to the driver.
This will help with future expansion of VF and FW communication.

With this in place now the VF and Virtual channel driver change to move over
to VSI id use is complete and is validated.
