pkt_sched: act_police: Fix a rate estimator test.
A commit c1b56878fb68e9c14070939ea4537ad4db79ffae "tc: policing requires a rate estimator" introduced a test which invalidates previously working configs, based on examples from iproute2: doc/actions/actions-general. This is too rigorous: a rate estimator is needed only when police's "avrate" option is used.
