PCI: Correct PCI_STD_RESOURCE_END usage

PCI_STD_RESOURCE_END is (confusingly) the index of the last valid BAR, not
the *number* of BARs. To iterate through all possible BARs, we need to
include PCI_STD_RESOURCE_END.

Fixes: 9fe373f9 ("PCI: Increase IBM ipr SAS Crocodile BARs to at least system page size")
