    nvme: Supress noise messages
    
    When we're suspending, we get messages about waiting for the controller
    to reset. These are in error: we're not waiting for it to reset. We put
    the recovery state as part of suspending, so we should suppress these as
    a false positive.
    
    Also remove a stray debug that's left over from earlier versions of
    the recovery code that no longer makes sense.
