netfilter: ip6t_srh: fix NULL pointer dereferences
[ Upstream commit 6d65561f3d5ec933151939c543d006b79044e7a6 ]
skb_header_pointer may return NULL. The current code dereference
its return values without a NULL check.
The fix inserts the checks to avoid NULL pointer dereferences.
Fixes: 202a8ff545cc ("netfilter: add IPv6 segment routing header 'srh' match")
