Subject: [net-next 02/16] ice: Add ice_get_main_vsi to get PF/main VSI

From: Anirudh Venkataramanan <anirudh.venkataramanan@...el.com>

There are multiple places where we currently use ice_find_vsi_by_type
to get the PF (a.k.a. main) VSI. The PF VSI by definition is always
the first element in the pf->vsi array (i.e. pf->vsi[0]). So instead
add and use a new helper function ice_get_main_vsi, which just returns
pf->vsi[0].
