LOG: [lldb][NFC] Fix flaky TestForwardDeclFromStdModule test

"[lldb/DataFormatters] Display null C++ pointers as nullptr" added an assumption
that the member we check for is always a nullptr, but it is actually never
initialized. That causes the test to randomly fail due to the pointer having
some random value that isn't 0.

Added:

Removed:
