Subject: ACPI/processor: Fix error handling in __acpi_processor_start()

From: Thomas Gleixner <[email protected]>

[ Upstream commit a5cbdf693a60d5b86d4d21dfedd90f17754eb273 ]

When acpi_install_notify_handler() fails the cooling device stays registered and the sysfs files created via acpi_pss_perf_init() are leaked and the function returns success.

Undo acpi_pss_perf_init() and return a proper error code.
