RFR: 8344018: Remove unlimited memory setting from TestScalarReplacementMaxLiveNodes

[Tobias Hartmann]

[JDK-8342612](https://bugs.openjdk.org/browse/JDK-8342612) increased the memory limit as a workaround for [JDK-8331295](https://bugs.openjdk.org/browse/JDK-8331295) which was found to be a separate issue ([JDK-8343038](https://bugs.openjdk.org/browse/JDK-8343038)). Let's remove the setting now that [JDK-8343038](https://bugs.openjdk.org/browse/JDK-8343038) got resolved by [JDK-8340824](https://bugs.openjdk.org/browse/JDK-8340824).

Thanks,
Tobias
