kdump: Execute kmsg_dump(KMSG_DUMP_PANIC) after smp_send_stop()

commit 62be73eafaa045d3233337303fb140f7f8a61135 upstream.

This patch moves kmsg_dump(KMSG_DUMP_PANIC) below smp_send_stop(),
to serialize the crash-logging process via smp_send_stop() and to
thus retrieve a more stable crash image of all CPUs stopped.
