Guenter Roeck a19038a200 hwmon: (pmbus) Fix return value from pmbus_update_byte_data() ...

pmbus_update_byte_data() is supposed to return a negative error code or 0.
However, if no change is made to the register, it actually returns the
register value. This can result in problems if the calling code explicitly
expects to see an error code or 0.

Fix it to return 0 on success or the error code as expected.

Fixes: 11c119986f ("hwmon: (pmbus) add helpers for byte write and read modify write")
