Re: dlls/opengl32/wgl.c: minor dealloc fix

According to...
    http://msdn2.microsoft.com/en-us/library/aa366701.aspx

lpMem
   [in] ...If this pointer is NULL, the behavior is undefined.

I personally dislike undefined behaviour -- If it is defined to NOP in wine 
that is sufficent for me.

But I think/tought I had a crash there tho...
