MdeModulePkg: Do not dump NULL padding resource descriptor
Add a check for ResourcePaddingDescriptors being a valid pointer in
DumpPpbPaddingResource() to prevent looping on memory not owned by
PciBusDxe. The ResourcePaddingDescriptors is initialized to NULL
when the PCI_IO_DEVICE structure is allocated and remains NULL if
no PCI hot plug controllers are present. This issue is only
observed when DEBUG_CODE() macros are enabled and was introduced
by the following patch:
