hw/arm/smmuv3: Handle translation faults according to SMMUPTWEventInfo
Previously, to check if faults are enabled, it was sufficient to check
the current stage of translation and check the corresponding
record_faults flag.
However, with nesting, it is possible for stage-1 (nested) translation
to trigger a stage-2 fault, so we check SMMUPTWEventInfo as it would
have the correct stage set from the page table walk.
