KVM: arm64: vgic-debug: Don't put unmarked LPIs

Browse source

If there were LPIs being mapped behind our back (i.e., between .start() and
.stop()), we would put them at iter_unmark_lpis() without checking if they
were actually *marked*, which is obviously not good.

Switch to use the xa_for_each_marked() iterator to fix it.
