Subject: re iproute2 - don't return error on success fix

Something is still broken also after commit b45e300 "libnetlink: don't
return error on success" - when error is returned, the error code is
success..

$ tc filter add dev enp33s0f0 protocol ip parent ffff: flower skip_sw
ip_flags nofirstfrag action drop && echo "success" || echo "failed"

RTNETLINK answers: Operation not supported
success
