net/sfc: let driver-internal flows use VF representor action

In the case of VF <--> VF representor pairs, these flows can
only collect VF traffic, so let them use generic flow action
PORT_REPRESENTOR, as part of re-using generic flow mechanism.

Currently, it does not allow to access VF representors since
they have no unique HW logical ports (m-ports). They all sit
on the same (representor proxy) m-port, while demultiplexing
of traffic uses ingress (VF) m-port value in packet metadata.
Traffic from arbitrary sources cannot be identified this way.
But, for VF traffic, it should be right to make an exception.

net/sfc: invalidate switch port entry on representor unplug

Once allocated, a switch port list entry always stays there,
even after unplugging the ethdev that created it. Currently,
the entry's ethdev ID is not cleared on unplug. Referencing
the ethdev ID of a detached representor from a flow rule is
going to succeed, which is a bug. Also, if the user unplugs
endpoint "A" representor and plugs one for "B" instead, the
latter will pick the same ethdev ID as the gone representor,
but it will have a new port list entry added for it. If the
user tries to reference the ethdev ID from a flow rule, the
code will fetch the wrong entry ("A" rather than "B") since
it sits closer to the list head. That is a serious bug, too.

Make the driver invalidate ethdev ID field on ethdev unplug.

Newer hardware may have arbitrarily complex controller configurations,

which allocates switch domains based on persistence of device
