Subject: [PATCH] spearmint: OpenGL2: Fix setting (unused) dlightBits

If num_dlights is 32, the dlightBits were set to 0. Now it's correctly set
to UINT_MAX. However the "tr.refdef.dlightBits" variable isn't actually used
for anything in the OpenGL2 renderer.

Fixes undefined behavior reported by cppcheck analyzer.
