Subject: [FIX] NET: Fix sch_api and sch_prio to properly set and detect the
	root qdisc

This is a patch from Patrick McHardy to fix the sch_api code, which I
went ahead and tested and made a slight fix to.  This also includes
the fix to sch_prio based on Patrick's patch.

The sch->parent handle should contain the parent qdisc ID.  When the
qdisc is the root qdisc (TC_H_ROOT), the parent handle should be the
value TC_H_ROOT.  This fixes sch_api to set this correctly on
qdisc_create() for both ingress and egress qdiscs.

Change this check in prio_tune() so that only the root qdisc can be
multiqueue-enabled; use sch->parent instead of sch->handle.
