This function shouldn't even exist.

Looks like a good way to introduce bugs. There's a reason we have
locking functions. The fact that in this case it's a stockfont that
won't get deleted, doesn't mean we can do this always. If you want
performance, keep a global pointer to the font and use
GDIOBJ_IncrementShareCount
