The bug is here: ret = i40e_add_macvlan_filter(hw, ch->seid, vdev->dev_addr, &aq_err);

The list iterator 'ch' will point to a bogus position containing HEAD if the list is empty or no element is found. This case must be checked before any use of the iterator, otherwise it will lead to a invalid memory access.
