mesa/main: Silence unused parameter warning

Just remove the _mesa_free_lighting_data function.  The body has been
empty since the shine table was moved into the tnl module (commit
ba1d921).

main/light.c:1216:46: warning: unused parameter 'ctx' [-Wunused-parameter]
 _mesa_free_lighting_data( struct gl_context *ctx )
                                              ^
