ipv6: Remove dependency of ipv6_frag_thdr_truncated on ipv6 module
IPV6=m
NF_DEFRAG_IPV6=y
ld: net/ipv6/netfilter/nf_conntrack_reasm.o: in function
`nf_ct_frag6_gather':
net/ipv6/netfilter/nf_conntrack_reasm.c:462: undefined reference to
`ipv6_frag_thdr_truncated'
Netfilter is depending on ipv6 symbol ipv6_frag_thdr_truncated. This
dependency is forcing IPV6=y.
Remove this dependency by moving ipv6_frag_thdr_truncated out of ipv6. This
is the same solution as used with a similar issues: Referring to
commit 70b095c843266 ("ipv6: remove dependency of nf_defrag_ipv6 on ipv6
module")
Fixes: 9d9e937b1c8b ("ipv6/netfilter: Discard first fragment not including all headers")
