    hyperv: Stop bus relations handling from falling through to eject
    
    The PCI_BUS_RELATIONS2 case lacks a break after queuing the reported
    devices.  It consequently processes the same packet as PCI_EJECT,
    interpreting device_count as the slot number.  If that value matches an
    existing child, the callback schedules an unintended device eject.
    
    End the relations case after processing the device list, matching the
    original PCI_BUS_RELATIONS handling.
