REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1563 SnpDxe initializes values for MemoryBarIndex and IoBarIndex to 0 and 1 respectively even if calls to PciIo->GetBarAttributes never return success. Later, if the BAR is used to perform IO/Mem reads/writes, a potentially non-existent BAR index may be accessed. This change initializes the values to an invalid BAR index (PCI_MAX_BAR) so the condition can be explicitly checked to avoid an invalid BAR access.
