[PATCH -next] iio: potentiometer: max5481: merge calls to of_match_device and of_device_get_match_data

[YueHaibing]

Drop call to of_match_device, which is subsumed by the subsequent
call to of_device_get_match_data.  The code becomes simpler, and a
temporary variable can be dropped.

Found by coccinelle.
