ice: tc: check src_vsi in case of traffic from VF

In case of traffic going from the VF (so ingress for port representor)
source VSI should be consider during packet classification. It is
needed for hardware to not match packets from different ports with
filters added on other port.

It is only for "from VF" traffic, because other traffic direction
doesn't have source VSI.

Set correct ::src_vsi in rule_info to pass it to the hardware filter.

For example this rule should drop only ipv4 packets from eth10, not from
the others VF PRs. It is needed to check source VSI in this case.
$tc filter add dev eth10 ingress protocol ip flower skip_sw action drop
