hwmon: (lm80) fix a missing check of the status of SMBus read
[ Upstream commit c9c63915519b1def7043b184680f33c24cd49d7b ]
If lm80_read_value() fails, it returns a negative number instead of the
correct read data. Therefore, we should avoid using the data if it
fails.
The fix checks if lm80_read_value() fails, and if so, returns with the
error number.
