Workbench: Fix crash editing in texture modes without uv layer

Browse Source 
When meshes has no uv layer, but has a texture assigned there was a uv
layer allocated which was corrupt. When no uv layer is available now
there won't be a vbo created. This might impact performance as the draw
cache does not cache this result.
