Switch the parameter from a pointer to a reference.
The only 2 callers in SfxChildWindow::CreateChildWindow
always pass a non-null param.
Using a reference makes clear that the param is always
non-null, allows dropping some null checks and makes
clear that those implementations previously unconditionally
dereferencing the pointer were unproblematic.
