net/sched: cls_u32: fix possible leak in u32_init_knode()
While investigating a related syzbot report,
I found that whenever call to tcf_exts_init()
from u32_init_knode() is failing, we end up
with an elevated refcount on ht->refcnt
To avoid that, only increase the refcount after
all possible errors have been evaluated.
Fixes: b9a24bb76bf6 ("net_sched: properly handle failure case of tcf_exts_init()")
