Update a switch rule' action from "to VSI" to "to VSI List"
should only happen when the same rule has been programmed with
a different fwd destination. This is already handled by below
code block:
m_entry = ice_find_adv_rule_entry(...)
if (m_entry) {
...
ice_adv_add_update_vsi_list(...)
}
The following ice_update_pkt_fwd_rule is unnecessary and should be
removed due to:
1) If a switch rule's action is still to VSI, which means, it is
the first time be issued, we don't need to update it "to VSI
List."
2) Actually the implementation does not match the comment, it still
update the rule with "to VSI" action.
