As the commit message said, this is to balance the preemption count.

We don't want to be preempted for the entire duration of kprobe
processing, preempt_disable() is called at the start of
kprobe_breakpoint_handler(), so preempt_enable_no_resched()
should also be called at each exit path.

So, it should keep the code as is.

Thanks,
