Pavel Skripkin 1148952dc6 net: sched: fix warning in tcindex_alloc_perfect_hash
[ Upstream commit 3f2db25009 ]

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()")
