ACPI: processor: idle: Fix NULL pointer dereference in hotplug path
A cpuidle_device might fail to register during boot, but the system can
continue to run. In such cases, acpi_processor_hotplug() can trigger
a NULL pointer dereference when accessing the per-cpu acpi_cpuidle_device.
So add NULL pointer check for the per-cpu acpi_cpuidle_device in
acpi_processor_hotplug.
