  r3.showdspf: fix accessing uninitialized pointer (#4246)

color2 pointer is not initialized and it is assigned a value
depending on a conditional. Potentially, in an execution path
if conditional fails, we would be accessing an uninitialized
pointer, whose behavior is undefined. Initialize the pointer
to NULL to avoid this.
