gdi32: Ensure child fonts have names

[Aric Stewart]

load_child_font calls neither WineEngCreateFontInstance nor GetEnumStructs.

It allocates the the child font structure above in the function sets the 
few fields it thinks it needs and then goes on. I see no evidence that 
it is being expected to have been set at any other point.
