Subject: [PATCH net-next v4 5/7] i40e: Consolidate checks whether given VSI is main
In the driver code there are 3 types of checks whether given
VSI is main or not:
1. vsi->type ==/!= I40E_VSI_MAIN
2. vsi ==/!= pf->vsi[pf->lan_vsi]
3. vsi->seid ==/!= pf->vsi[pf->lan_vsi]->seid
All of them are equivalent and can be consolidated. Convert cases
2 and 3 to case 1.
