MainAndroid: Thread Correctness In WriteJitBlockLogDump 

In a race condition, the core could shut down between the `JitInterface::GetCore` nullptr check and the `JitInterface::JitBlockLogDump` call which constructs a `CPUThreadGuard`. In this scenario, nothing horrible happens—`JitBlockLogDump` also checks for a nullptr—but it would be a failure to display the correct feedback to the user.
