Subject: tipc: make sure IPv6 header fits in skb headroom

From: Richard Alpe <richard.alpe@ericsson.com>

commit 9bd160bfa27fa41927dbbce7ee0ea779700e09ef upstream.

Expand headroom further in order to be able to fit the larger IPv6
header. Prior to this patch this caused a skb under panic for certain
tipc packets when using IPv6 UDP bearer(s).
