A problem with comctl32

[DanteAliegri]

Hey, I've come across what appears to be a
simple problem in comctl32.
When running icq99b, wine was dying in imagelist.c while trying to 
dereference a null pointer.
Upon looking at the file,  there was code for returning FALSE if that 
pointer was null,
thus I felt it being null may be a valid choice.
I made the attached change, and the problem was fixed.
Comments?
