net: sparx5: flower: check for unsupported control flags
Use flow_rule_is_supp_control_flags() to reject filters with
unsupported control flags.
In case any unsupported control flags are masked,
flow_rule_is_supp_control_flags() sets a NL extended
error message, and we return -EOPNOTSUPP.
Only compile-tested.
