ubi: Do not drop UBI device reference before using
[ Upstream commit e542087701f09418702673631a908429feb3eae0 ]
The UBI device reference is dropped but then the device is used as a
parameter of ubi_err. The bug is introduced in changing ubi_err's
behavior. The old ubi_err does not require a UBI device as its first
parameter, but the new one does.
