[PATCH] rcu-tasks: Fix compilation warning with !CONFIG_TASKS_RCU and CONFIG_TINY_RCU

[Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx>]

Commit 8344496e8b49 ("rcu-tasks: Conditionally compile
show_rcu_tasks_gp_kthreads()") introduced conditional compilation of
several functions, but forgot one occurrence of
show_rcu_tasks_classic_gp_kthread() that causes the compiler to warn of
an unused static function. Fix it.

Fixes: 8344496e8b49 ("rcu-tasks: Conditionally compile show_rcu_tasks_gp_kthreads()")
