[RFC v7 21/26] hw/arm/smmuv3: Fill the IOTLBEntry leaf field on NH_VA invalidation |

Let's propagate the leaf attribute throughout the invalidation path.
This hint is used to reduce the scope of the invalidations to the
last level of translation. Not enforcing it induces large performance
penalties in nested mode.
