    Revert "net: Change number of netlink repair"
    
    This reverts commit 9cdd731a629a0c83ae8864759944aa62d9c8bd5b.
    
    We need to release criu package along with the vzkernel with
    netlink repair number changed, but we don't want to release
    criu userspace package right now, only kernel =>
    
    revert the netlink repair number shift for now.
