drivers: sensor: tmp1075: remove redundant module name in log message

The tmp1075 driver already registers a log module using
LOG_MODULE_REGISTER(TMP1075, CONFIG_SENSOR_LOG_LEVEL).
This ensures that all log messages are prefixed with "TMP1075".
The existing LOG_ERR message redundantly includes "tmp1075",
which is unnecessary.
