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.
Remove FLOW_DIS_FIRST_FRAG specific error message,
and treat it as any other unsupported control flag.
Only compile-tested.

I tend to read the above ack as the 2nd option, but given this is only build tested I guess the first would be better... Thanks, Paolo
