Getting a zpci_dev via get_zdev_by_bus() uses the long lived reference held in zbus->function[devfn]. This is accounted for in pcibios_add_device() and pcibios_release_device(). Therefore there is no need to increment the reference count in get_zdev_by_bus() as is done for get_zdev_by_fid(). Instead callers must not access the device after pcibios_release_device() was called which is necessary for common PCI code anyway. With this though the very similar naming may be misleading so rename get_zdev_by_bus() to zdev_from_bus() emphasizing that we are directly referencing the zdev via the bus.
