The vgic debug iterator is the final user of vgic_copy_lpi_list(), but is a bit more complicated to transition to something else. Use a mark in the LPI xarray to record the indices 'known' to the debug iterator. Protect against the LPIs from being freed by associating an additional reference with the xarray mark. Rework iter_next() to let the xarray walk 'drive' the iteration after visiting all of the SGIs, PPIs, and SPIs.
