Two vulkan binding_model cases failed due to "timeout" on Android 10 with mesa 19.1.6.

We didn't have this issue with mesa 19.0.6. Need double confirm, if this is a new regression with mesa 19.1.6?
With upstream master branch(e4a52bd), following case could pass, need double check which could help fix following case on master branch.
