False positive warnings and validation crash

[Plagman]

If you download this trace:

https://www.dropbox.com/s/ycsy007lli0im5e/witcher3.7z?dl=0

Run it with apitrace.exe with DXVK binaries (d3d11.dll and dxgi.gll) dropped into the same directory; observe these sort of errors:

VkPhysicalDeviceFeatures::shaderStorageImageWriteWithoutFormat but is not enabled on the device

I'm told this particular trace also causes a crash when validation is enabled.

I was finally able to reproduce this issue with the following setup:

• wine 3.11
• apitrace-msvc-latest (https://people.freedesktop.org/~jrfonseca/apitrace/ 2018-07-04)
• DXVK and witcher3.trace from issue descriptoin
• NVIDIA driver 396.24.02 (beta version with VK_EXT_vertex_attribute_divisor required by DXVK)

Resulting in the following unique validation errors:

I'll start digging around with debugger to see why the shader validation code is printing those errors. One final note: I was not able to reproduce the crash. The attached trace exits cleanly with validation enabled.
