[PATCH] frv: replace now removed pci_bus_b() causing build failure

[Paul Gortmaker <paul.gortmaker@windriver.com>]

In commit 94e6a9b93064b49024b8701d2d81fcb4a821fa09 ("PCI: Remove
pci_bus_b() and use list_for_each_entry() directly") the function
pci_bus_b() was removed, but one instance of its usage was missed.

Replace it in the same fashion that the original commit did.
