iio: Fix iio_multiply_value use in iio_read_channel_processed_scale

Browse source

The function iio_multiply_value returns IIO_VAL_INT (1) on success or a
negative error number on failure, while iio_read_channel_processed_scale
should return an error code or 0. This creates a situation where the
expected result is treated as an error. Fix this by checking the
iio_multiply_value result separately, instead of passing it as a return
value.
