lavapipe assert fails on Windows

Trying to run Vulkan-Cube (https://github.com/raubee/Vulkan-Cube) on lavapipe on Windows, and it assert fails with:

Device 0 : llvmpipe (LLVM 15.0.5, 128 bits)
Assertion failed: chain->base.blit.type == WSI_SWAPCHAIN_BUFFER_BLIT, file ../../src/vulkan/wsi/wsi_common_win32.cpp, line 648

The following patch will make it work, but I don't know if it is a proper fix.
