intel_idle: Don't overreact to a cpuidle registration failure.
The helper function, intel_idle_cpu_init, registers one new device
with the cpuidle layer. If the registration should fail, that
function immediately calls intel_idle_cpuidle_devices_uninit() to
unregister every last CPU's device. However, it makes no sense to do
so, when called from the hot plug notifier callback.
This patch moves the call to intel_idle_cpuidle_devices_uninit()
outside of the helper function to the one call site that actually
needs to perform the de-registrations.
