qintrusivelvist_p.h: Silence nullpointer subtraction warning
Fixing this class to avoid the UB here is not worth the effort. Using a
pointer which is not nullptr "works", but does not change the underlying
fact that only the offsetof macro is allowed this trickery. So instead
of hiding the issue, we explicitly silence it for now.
