netdev-linux: Dump all queues, not just direct children of the root.

A netdev-linux traffic control implementation has to dump all of a port's
traffic classes in a couple of different situations.  start_queue_dump()
is supposed to do that.  But it was specifying TC_H_ROOT as tcm_parent,
which only dumped classes that were direct children of the root.  This
commit changes tcm_parent to 0, which obtains all traffic classes
regardless of parent.
