pci_host_generic: Pass a valid end address in generic_pcie_translate_resource

Browse Source 
The generic_pcie_containing_range helper added in commit d79b6b8ec2
assumed that the passed in (start, end) range used to locate the
containing mapping range was a valid address range (with end >=
start).  The previous version of
generic_pcie_translate_resource_common only used the start address to
locate a mapping range, so the end address of 0 did not matter, but an
end of 0 now causes the first range to match and an incorrect
translation for resources using a later range.
