Revert "hostdev: Use actual device when reattaching"
    
    This reverts commit ee4cfb56436b50345b072c706b87aff82e06d760.
    
    Since we're still not persisting our bookkeeping lists across
    daemon restarts, we might have lost some information
    virPCIDeviceReattach() relies on, for example whether the
    device needs to be unbound from the stub driver.
    
    As a result, if the daemon has been restarted in the meantime,
    the device might end up remaining bound to the stub driver even
    after 'virsh nodedev-reattach' or similar has been called, with
    no way of giving it back to the host short of messing with
    sysfs behind libvirt's back.
    
    Revert back to the previous behavior of always trying to bind
    the device to the host driver, regardless of its status when it
    was detached, until persistent bookkeeping lists have been
    implemented.
