char/adi: Use min_t(size_t,,) in adi_read() + adi_write()

Replace min() and manual casting of MAX_BUF_SZ with min_t(size_t,,) in
both adi_read() and adi_write().

This matches the initial buffer size calculation:

	ver_buf_sz = min_t(size_t, count, MAX_BUF_SZ);

and makes the code more consistent. No functional changes intended.
