ipv6: fix possible seqlock deadlock in ip6_finish_output2
[ Upstream commit 7f88c6b23afbd31545c676dea77ba9593a1a14bf ]
IPv6 stats are 64 bits and thus are protected with a seqlock. By not
disabling bottom-half we could deadlock here if we don't disable bh and
a softirq reentrantly updates the same mib.
