net/sched: cbs: Set default link speed to 10 Mbps in cbs_set_port_rate

[ Upstream commit 1c6c09a0ae62fa3ea8f8ead2ac3920e6fff2de64 ]

The discussion to be made is absolutely the same as in the case of
previous patch ("taprio: Set default link speed to 10 Mbps in
taprio_set_picos_per_byte"). Nothing is lost when setting a default.
