Merge branch 'validation_fix_api_command_buffers' into 'vulkan-cts-1.0-dev'
dEQP-VK.api.command_buffers: remove bad test
I think two test cases were wrong -- they allocated zero command buffers which shouldn't be allowed. Layers treat it as an error and I filed a spec bug because it's not stated explicitly. I'm removing these two tests.
See #357 for details on validation task.
### Vulkan spec issue
- [Issue 292](https://gitlab.khronos.org/vulkan/vulkan/issues/292) - VkCommandBufferAllocateInfo valid usage
