    Low: crmd: avoid core dump if remote connection doesn't exist
    
    do_lrm_invoke() calls synthesize_lrmd_failure() with a NULL lrm_state if asked
    to perform an operation on a remote node that has never been connected locally.
    Previously, this would cause a null dereference in construct_op(). Now,
    construct_op() handles the situation reasonably.
