commit 3be43be0bbb1b8f32f7e6c42d06f5b0a1f1ee467

Fix crash in IndexDataManagerPerfTest.

Using a mock BufferFactory would sometimes leave us with a nullptr in
the VertexBufferInterface class. This would lead to a null deref in
the perf tests only. Fix this by adding a null check.

The benchmark hasn't failed on the bot for more than a week (last failure: https://build.chromium.org/p/chromium.perf/builders/Win%207%20Nvidia%20GPU%20Perf%20%282%29/builds/4723 ). Therefore, I'm marking this issue as fixed. Please re-open if the failures occur again.
