[PATCH iwl-net 1/10] ice: fix mirroring to VSI list

[Aleksandr Loktionov <aleksandr.loktionov@intel.com>]

From: Michal Swiatkowski <michal.swiatkowski@intel.com>

Rules whose action can be "to VSI list" should have VSI count set to 1
after creation. There was a lack of it in case of mirroring action. Fix
it by setting correct VSI count also for mirror rules.

Reproduction:
  tc filter add dev eth5 ingress protocol arp prio 6301 flower skip_sw \
    dst_mac ff:ff:ff:ff:ff:ff action mirred egress mirror dev eth9
  tc filter add dev eth5 ingress protocol arp prio 6201 flower skip_sw \
    dst_mac ff:ff:ff:ff:ff:ff action mirred egress mirror dev eth10

  tc filter del dev eth5 prio 6301 ingress

The last command removes the rule, but should only remove one VSI from
the forward list. Without the fix:

  tc filter del dev eth5 prio 6201 ingress

results in an error during removing the rule.
