    enic: Report device enable failures to iflib
    
    Do not publish a running interface after vnic_dev_enable_wait() fails.
    Run the existing stop cleanup for the queues configured before the enable
    request, then report initialization failure to iflib.
    
    Mark those queues as needing cleanup before submitting the enable request
    so the stopped-state shortcut cannot skip the unwind.
