ACPI: fan: cleanup resources in the error path of .probe()

Browse source

[ Upstream commit c759bc8e90 ]

Call thermal_cooling_device_unregister() and sysfs_remove_link() in the
error path of acpi_fan_probe() to fix possible memory leak.

This bug was found by an experimental static analysis tool that I am
developing.
