Tweaking workaround to use fallback with null buffer

Browse Source 
- This case still shouldn't ever happen, but we're still
  getting crashes. It looks like the call to wrapHardwareBuffer
  will always create a hw buffer even if the graphic buffer
  is null, and the internal call to wrap the hw buffer may
  not have the flags if a null buffer is provided.

Bug: 157562905
Test: Haven't been able to reproduce
