thermal/drivers/rz2gl: Add error check for reset_control_deassert()
If reset_control_deassert() fails, then we won't be able to access the device registers. Therefore check the return code of reset_control_deassert() and bail out in case of error. While at it replace the parameter "&pdev->dev" -> "dev" in devm_reset_control_get_exclusive().
