ACPI: processor: idle: Fix memory leak when register cpuidle device failed
[ Upstream commit 11b3de1c03fa9f3b5d17e6d48050bc98b3704420 ]
The cpuidle device's memory is leaked when cpuidle device registration
fails in acpi_processor_power_init(). Free it as appropriate.
Fixes: 3d339dcbb56d ("cpuidle / ACPI : move cpuidle_device field out of the acpi_processor_power structure")
