    ixgbe: reject VF requests before CTS
    
    A VF that sends a non-reset request before completing reset negotiation
    has not received CTS.  The PF ignores the request but currently reports
    success, leaving the VF with a false view of the programmed state.
    
    Return failure for the ignored request.  This restores the behavior lost
    when the mailbox helpers were renamed.
    
    Fixes:          36c516b31136 ("ixgbe: update if_sriov to use the new mailbox apis")
    MFC after:      1 week
