Subject: ice: Add ice_get_main_vsi to get PF/main VSI
Patch-mainline: v5.4-rc1
Git-commit: 208ff75135cd68a42638221626d2af2f8f17a3cb
References: jsc#SLE-7926

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].
