Pavel Skripkin eff9dabc00 net: sched: fix warning in tcindex_alloc_perfect_hash 
[ Upstream commit 3f2db250099f46988088800052cdf2332c7aba61 ]

Syzbot reported warning in tcindex_alloc_perfect_hash. The problem
was in too big cp->hash, which triggers warning in kmalloc. Since
cp->hash comes from userspace, there is no need to warn if value
is not correct

Fixes: b9a24bb76b ("net_sched: properly handle failure case of tcf_exts_init()")
