hwmon: (lm80) fix a missing check of bus read in lm80 probe

In lm80_probe(), if lm80_read_value() fails, it returns a negative
error number which is stored to data->fan[f_min] and will be further
used. We should avoid using the data if the read fails.

The fix checks if lm80_read_value() fails, and if so, returns with the
error number.
