[IPV6]: Ensure to use icmpv6_socket in non-preemptive context.
We saw following trace several times: |BUG: using smp_processor_id() in preemptible [00000001] code: httpd/30137 |caller is icmpv6_send+0x23/0x540 | [<c01ad63b>] smp_processor_id+0x9b/0xb8 | [<c02993e7>] icmpv6_send+0x23/0x540 This is because of icmpv6_socket, which is the only one user of smp_processor_id() in icmpv6_send(), AFAIK. Since it should be used in non-preemptive context, let's defer the dereference after disabling preemption (by icmpv6_xmit_lock()).
