[NTOS]: Don't assume that ANY fault in the system address range, not associated to a memory area, might be ARM3. Instead, since this hack only exists for early boot page pool support, make only treat this as an ARM3 fault when it happens in the paged pool area or higher. Leads to more direct Mm crashes when invalid page access happens, instead of infinite "PAGE FAULT ON PAGE TABLES".
