cpuidle_device::safe_state_index need to be initialized before use,
so assign the driver's safe_state_index to it.

Hey, good catch. We are lucky the safe_state_index is always zero.
I think we can simplify the code by removing the safe_state_index from
the cpuidle_device structure and use the one in the cpuidle_driver
structure in coupled.c
