This commit applies another _rcuidle suffix to fix an RCU use from
idle.

===============================
[ INFO: suspicious RCU usage. ]
4.6.0-rc5-next-20160426+ #1122 Not tainted
-------------------------------
include/trace/events/rpm.h:69 suspicious rcu_dereference_check() usage!

other info that might help us debug this:


RCU used illegally from idle CPU!
rcu_scheduler_active = 1, debug_locks = 0
RCU used illegally from extended quiescent state!
1 lock held by swapper/0/0:
 #0:  (&(&dev->power.lock)->rlock){-.-...}, at: [<c052e3dc>] __pm_runtime_resume+0x3c/0x64
