rcu-tasks: Fix show_rcu_tasks_trace_gp_kthread buffer overflow

In the Linux kernel, the following vulnerability has been resolved:

rcu-tasks: Fix show_rcu_tasks_trace_gp_kthread buffer overflow

There is a possibility of buffer overflow in
show_rcu_tasks_trace_gp_kthread() if counters, passed
to sprintf() are huge. Counter numbers, needed for this
are unrealistically high, but buffer overflow is still
possible.

Use snprintf() with buffer size instead of sprintf().
