From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>
usb_hcd_pci_probe() searches for an I/O BAR using a combination of
PCI_STD_NUM_BARS (to control loop iteration) and PCI_ROM_RESOURCE (to check
whether the loop exits without finding anything).
Use PCI_STD_NUM_BARS consistently.
No functional change since PCI_STD_NUM_BARS == PCI_ROM_RESOURCE, but this
removes a dependency on that relationship and makes the code read better.
Fixes: c9c13ba428ef ("PCI: Add PCI_STD_NUM_BARS for the number of standard
BARs")
