Don't increase the reference count if dynamic_cast failed
If the dynamic_cast failed in QSharedPointer::dynamicCast or
qSharedPointerDynamicCast, we should avoid creating the QSharedPointer
that shares the weak and strong reference counts. In Qt 5, this does
not imply a leak since the original pointer is stored internally for
deletion. In Qt 4 it implies a leak under certain circumstances, which
this change fixes.
