PCI: Always have realloc_head in __assign_resources_sorted()

Browse source

Add a dummy list to always have a non-NULL realloc head in
__assign_resources_sorted() as it allows only checking list_empty().

In future, it would be good to ensure all callers provide a valid
realloc_head but that is relatively complex to do in practice and not
necessary for the subsequent optional resource handling fix.
