of/pci: Remove duplicate kfree in of_pci_get_host_bridge_resources()

Commit d2be00c0fb5a ("of/pci: Free resources on failure in
of_pci_get_host_bridge_resources()") fixed the error path so it frees
everything on the "resources" list.  That list includes the bus_range, so
we should not free it again.

Remove the superfluous free of bus_range.
