Flush console log from kernel_power_off()
[ Upstream commit 6ea9a1781c70a8be1fcdc49134fc1bf4baba8bca ]
Kernels built with CONFIG_PREEMPT_RT=y can lose significant console output
and shutdown time, which hides shutdown-time RCU issues from rcutorture.
Therefore, make pr_flush() public and invoke it after then last print
in kernel_power_off().
