rcu: Initialize at declaration time in rcu_exp_handler()
This commit moves the initialization of the CONFIG_PREEMPT=n version of the rcu_exp_handler() function's rdp and rnp local variables into their respective declarations to save a couple lines of code. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
