    uqmi: wait forever registration if timeout set to 0
    
    Give possibility to wait forever the registration by setting timeout
    option to 0.
    
    No timeout can be useful if the interface starts whereas no network is
    available, because at the end of timeout the interface will be stopped
    and never restarted.
