kmsg_dump: add kmsg_dump() calls to the reboot, halt, poweroff and emergency_restart paths
We need to know the reason why system rebooted in support service. However, we can't inform our customers of the reason because final messages are lost on current Linux kernel. This patch improves the situation above because the final messages are saved by adding kmsg_dump() to reboot, halt, poweroff and emergency_restart path.
