[PATCH] iio: gyro: adis16136: use scnprintf instead of snprintf

[Rohit Sarkar]

scnprintf returns the actual number of bytes written into the buffer as
opposed to snprintf which returns the number of bytes that would have
been written if the buffer was big enough. Using the output of snprintf
may lead to difficult to detect bugs.

Thanks,
Rohit
