PCI: Add missing MEM_64 mask in pci_assign_unassigned_bridge_resources()

In 5b28541552ef ("PCI: Restrict 64-bit prefetchable bridge windows to
64-bit resources"), we added IORESOURCE_MEM_64 to the mask in
pci_assign_unassigned_root_bus_resources(), but not to the mask in
pci_assign_unassigned_bridge_resources().

Add IORESOURCE_MEM_64 to the pci_assign_unassigned_bridge_resources() type
mask.
