hwmon: (stts751) buffer overrun on wrong chip configuration
If stts751 hw by some reason reports conversion rate bigger then 9:
ret = i2c_smbus_read_byte_data(priv->client, STTS751_REG_RATE);
then dereferencing stts751_intervals[priv->interval] leads to buffer
overrun.
The patch adds sanity check for value stored on chip.
Found by Linux Driver Verification project (linuxtesting.org).
