ARM: cpuidle: Don't register the driver when back-end init returns -ENXIO
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.
Fixes: a0d46a3dfdc3 (ARM: cpuidle: Register per cpuidle device)
