Alexandre Ferrieux 789f9963bd net: sched: cls_u32: Fix u32's systematic failure to free IDR entries for hnodes.
[ Upstream commit 73af53d82076bbe184d9ece9e14b0dc8599e6055 ]

To generate hnode handles (in gen_new_htid()), u32 uses IDR and
encodes the returned small integer into a structured 32-bit
word. Unfortunately, at disposal time, the needed decoding
is not done. As a result, idr_remove() fails, and the IDR
fills up. Since its size is 2048, the following script ends up
with "Filter already exists":

  tc filter add dev myve $FILTER1
  tc filter add dev myve $FILTER2
  for i in {1..2048}
  do
    echo $i
    tc filter del dev myve $FILTER2
    tc filter add dev myve $FILTER2
  done

This patch adds the missing decoding logic for handles that
deserve it.

Fixes: e7614370d6 ("net_sched: use idr to allocate u32 filter handles")
