    tevent: Clarify apparently useless conditions
    
    Comment on two similar conditions in tevent_standard.c, which,
    otherwise, at a first glance, seem useless, i.e. always true.
    
    The conditions checking glue->epoll_ops for being non-NULL, imply that
    it *can* be NULL. A casual reader would not generally expect a "member"
    function to modify its container's pointer in a container higher up, and
    would assume that glue->epoll_ops could be NULL before the call,
    resulting in a near-NULL pointer dereference.
    
    However, in this case epoll_ops is indeed cleared in those "member"
    functions, in the case of an epoll interface failure, to signify
    fallback to poll interface.
