[PATCH linux dev-4.13 4/5] pmbus (core): Use driver callbacks in pmbus_get_fan_rate()

[Andrew Jeffery]

The driver may have overridden the pmbus_read_byte_data() callback, so
make sure we use that to achieve expected behaviour.

This helps in the MAX31785 case where we may need to perform a one-shot
retry of transfers in the face of a failure.
