[PATCH 29/48] rcu: Remove redundant CONFIG_PROVE_RCU #if condition

From: "Paul E. McKenney" <paulmck@kernel.org>

The #if condition controlling the rcu_preempt_sleep_check() definition
has a redundant check for CONFIG_PREEMPT_RCU, which is already checked
for by an enclosing #ifndef. This commit therefore removes this redundant
condition from the inner #if.
