Subject: [PATCH v2 4/8] iio: core: Use min() instead of min_t() to make code more robust

min() has strict type checking and preferred over min_t() for
unsigned types to avoid overflow. Here it's unclear why min_t()
was chosen since both variables are of the same type. In any
case update to use min().
