[PATCH] PCI: rockchip: Remove redundant "valid device" check

[Bjorn Helgaas]

From: Bjorn Helgaas <bhelgaas at google.com>

In rockchip_pcie_valid_device(), we do the exact same test twice:

  if (bus->number == rockchip->root_bus_nr && dev > 0)
    return 0;
  if (bus->number == rockchip->root_bus_nr && dev > 0)
    return 0;

We only need to do it once, so remove one of them.
