Daniel Fu 6ae69a801b cpuidle: Check the result of cpuidle_get_driver() against NULL ...

commit 3b9c10e980 upstream.

If the current CPU has no cpuidle driver, drv will be NULL in
cpuidle_driver_ref().  Check if that is the case before trying
to bump up the driver's refcount to prevent the kernel from
crashing.
