virgl: also mark sampler views as dirty
When texture buffers are used as images in compute shaders, the guest never sees the modified data since the TBO is always marked as clean. Fixes most dEQP-GLES31.functional.image_load_store.buffer.* tests. Example test cases: dEQP-GLES31.functional.image_load_store.buffer.load_store.r32ui dEQP-GLES31.functional.image_load_store.buffer.qualifiers.coherent_r32f dEQP-GLES31.functional.image_load_store.buffer.format_reinterpret.rgba8_rgba8ui Note: virglrenderer side patch also needed to bind TBOs correctly Reviewed-by: Dave Airlie <airlied@redhat.com>
