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().
