netfilter: IPv6: initialize TOS field in REJECT target module
commit 4319cc0cf5bb894b7368008cdf6dd20eb8868018 upstream.
The IPv6 header is not zeroed out in alloc_skb so we must initialize
it properly unless we want to see IPv6 packets with random TOS fields
floating around. The current implementation resets the flow label
but this could be changed if deemed necessary.
We stumbled upon this issue when trying to apply a mangle rule to
the RST packet generated by the REJECT target module.
