ice: refactor struct ice_vsi_cfg_params to be inside of struct ice_vsi

Refactor struct ice_vsi_cfg_params to be embedded into struct ice_vsi.
Prior to that the members of the struct were scattered around ice_vsi,
and were copy-pasted for purposes of reinit.
Now we have struct handy, and it is easier to have something sticky
in the flags field.
