From: Marcin Szycik <marcin.szycik@linux.intel.com>

Adding/updating VSI list rule, as well as allocating/freeing VSI list
resource are called several times with type ICE_SW_LKUP_LAST, which fails
because ice_update_vsi_list_rule() and ice_aq_alloc_free_vsi_list()
consider it invalid. Allow calling these functions with ICE_SW_LKUP_LAST.

This fixes at least one issue in switchdev mode, where the same rule with
different action cannot be added, e.g.:

  tc filter add dev $PF1 ingress protocol arp prio 0 flower skip_sw \
    dst_mac ff:ff:ff:ff:ff:ff action mirred egress redirect dev $VF1_PR
  tc filter add dev $PF1 ingress protocol arp prio 0 flower skip_sw \
    dst_mac ff:ff:ff:ff:ff:ff action mirred egress redirect dev $VF2_PR
