ARM: cpuidle: Don't register the driver when back-end init returns -ENXIO
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.
