This helper can be used by drivers, that doesn't support
any control flags, to reject any attempt to install rules
with control flags.
This is aimed at drivers, which uses flow_rule_match_control(),
but doesn't implement any control flags.
Only compile-tested.

How about to squash this change with series I patch since they have similar functions for driver to use.

Sorry for confusing you. I mean if you can squash this change with your first patch which introduce the function of flow_rule_no_unsupp_control_flags.
