According to isl_gfx7.c:264, the display engine does not support Y tiled buffers prior to Skylake. But we exposed I915_FORMAT_MOD_Y_TILED even when querying for a list of modifiers with __DRI_IMAGE_USE_SCANOUT set, which we can't support. That led to crashes later when we tried to create such an image, and isl rightly denied it. This duplicates a bit of code from ISL, but the isl_gfx6_filter_tiling function that we ought to use to filter things relies on surf_info, which we don't have at this stage. This is probably good enough. Fixes crashes in wflinfo sincec03e79d783, but the bug exists before that and it's probably worth a stable backport even without that patch.
