[Bastien Nocera <hadess src gnome org>]

    Fix adapter not going powered when coming back from hard-block
    
    1. Soft-kill the adapter
    2. Hard-kill the adapter
    3. Disable hard-kill
    4. Disable soft-kill
    
    At 4., the adapter will be present, unblocked, but still
    unpowered. Call SetPower on it to make sure it is revived.
