rhi: vk: Fix up some legacy queue (family) index inconsistencies

Relevant mainly if we want to consistently expose these as the
theoretically correct uint32_t/quint32 from Qt Quick's
QSGRendererInterface. (not that int is not sufficient for
indexing the typical 3-4 families and 2-16 queues per family)

Some checks are not actually needed since the family index
must always be valid after create().

Pick-to: 6.5
Task-number: QTBUG-108895
