ice: use src VSI instead of src MAC in slow-path

The use of a source MAC to direct packets from the VF to the corresponding
port representor is only ok if there is only one MAC on a VF. To support
this functionality when the number of MACs on a VF is greater, it is
necessary to match a source VSI instead of a source MAC.

Let's use the new switch API that allows matching on metadata.

If MAC isn't used in match criteria there is no need to handle adding
rule after virtchnl command. Instead add new rule while port representor
is being configured.

Remove rule_added field, checking for sp_rule can be used instead.
Remove also checking for switchdev running in deleting rule as it can be
called from unroll context when running flag isn't set. Checking for
sp_rule covers both context (with and without running flag).

Rules are added in eswitch configuration flow, so there is no need to
have replay function.
