ACPI: button: Add missing device class clearing on probe failures 

Commit e18947038b ("ACPI: driver: Do not set acpi_device_class()
unnecessarily") modified acpi_button_remove() to clear the device class
field in struct acpi_device on driver removal, but it should also have
updated the rollback path in acpi_button_probe(), which it didn't do,
so do it now.
