ARM: cpuidle: Don't register the driver when back-end init returns -E…
…NXIO commit 763f191af51f127cf8e69cd361f50bf6180768a5 upstream. There's no point to register the cpuidle driver for the current CPU, when the initialization of the arch specific back-end data fails by returning -ENXIO. Instead, let's re-order the sequence to its original flow, by first trying to initialize the back-end part and then act accordingly on the returned error code. Additionally, let's print the error message, no matter of what error code that was returned.
