[PATCH v2 4/8] iio: inkern: return valid type on raw to processed conversion

[Liam Beguin <liambeguin@gmail.com>]

From: Liam Beguin <lvb@xiphos.com>

iio_convert_raw_to_processed_unlocked() applies the offset and scale of
a channel on it's raw value.
The processed value returned is always an integer. Return IIO_VAL_INT so
that consumers can use this return value directly.
