[LARTC] sch_prio.c and sch_csz.c 2.4.20 patches for correct filter destroying

[Dimitry V. Ketov]

Recently I've posted these patches in lkml and netdev mailing lists.
Just repeating them here if someone is interesting: sch_prio.c and
sch_csz.c do not destroy their filter lists, when someone deletes qdisc
from interface without explicit filter deleting. So here is the patches.
:)
