[IL2CPP] Crash on il2cpp::vm::Field::GetValueObjectForThread in build when MulticastOption is used inside SetSocketOption

IL2CPP

-

Steps to reproduce:
1. Open the attached project ("1199942.zip")
2. Build and run the project (File -> Build Settings... -> Build And Run)

Reproducible with: 2018.4.13f1, 2019.2.13f1, 2019.3.0b12, 2020.1.0a14
Couldn't test with 2017.4 because IL2CPP is not available on that stream.
