> Currently when a VF VSI calls ice_vsi_release() and ice_vsi_setup() it
> subsequently clears/sets the VF cached variables for lan_vsi_idx and
> lan_vsi_num. This works fine, but can be improved by handling this in the VF
> specific VSI release and setup functions.
> 
> Also, when a VF VSI is setup too many parameters are passed that can be
> derived from the VF. Fix this by only calling VF VSI setup with the bare
> minimum parameters.
> 
> Also, add functionality to invalidate a VF's VSI when it's released and/or
> setup fails. This will make it so a VF VSI cannot be accessed via its cached
> vsi_idx/vsi_num in these cases.
> 
> Finally when a VF's VSI is invalidated set the lan_vsi_idx and lan_vsi_num to
> ICE_NO_VSI to clearly show that there is no valid VSI associated with this VF.
