Subject: [PATCH V2] mfd: timberdale: remove unnecessary pci_set_drvdata()

The driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the
device driver data to NULL. It also removes unnecessary label such
as 'err_request'.

Changes since v1:
- Removed unnecessary label such as 'err_request'.
