Have OpenGL2 "map $lightmap" check for NULL tr.lightmaps too

Browse source 
Zero length lightmap lump will have NULL tr.lightmaps.

OpenGL1 already has this check, because r_vertexLight 1
would crash Team Arena. OpenGL2 does not disable loading lightmaps
when r_vertexLight is 1 though, so it does not have that issue.
