qos: Remove min-rate requirement for linux-htb and linux-hfsc.

Browse Source 
One could quite reasonably desire to create a queue with no
min-rate.  For example, a default queue could be reasonably
configured without a min-rate or a max-rate.  This commit removes
the requirement that min-rate be configured on all queues.  If not
configured, defaults to something very small.
