ipv6: some ipv6 statistic counters failed to disable bh
After commit c15b1ccadb323ea ("ipv6: move DAD and addrconf_verify
processing to workqueue") some counters are now updated in process context
and thus need to disable bh before doing so, otherwise deadlocks can
happen on 32-bit archs. Fabio Estevam noticed this while while mounting
a NFS volume on an ARM board.
As a compensation for missing this I looked after the other *_STATS_BH
and found three other calls which need updating:
1) icmp6_send: ip6_fragment -> icmpv6_send -> icmp6_send (error handling)
2) ip6_push_pending_frames: rawv6_sendmsg -> rawv6_push_pending_frames -> ...
(only in case of icmp protocol with raw sockets in error handling)
3) ping6_v6_sendmsg (error handling)
Fixes: c15b1ccadb323ea ("ipv6: move DAD and addrconf_verify processing to workqueue")
