To close popup model there is method closeModal().

Updated code:

function ($) {
    "use strict";
    // Review form 
    var x = {
        type: 'popup',
        responsive: true,
        innerScroll: true,
        buttons: false,
        title: "Header contant",
        modalClass: "popup-center abc-product-review",
        clickableOverlay: true,
        heightStyle: "content"
    };
    var a = $('#review-form-content-wrapper').modal(x);
    $(".add-your-review").click(function () {
        var status = $(this).attr('data-status');
        if (status === 'logged in')
            a.modal("openModal");
        else
            alert("Please loggin");
    });
return function (config) {
        $('#review-form').on("click", "#review-submit", function () {
            var form_data = $("#review-form").serialize();
            var reviewurl = config.url;
            $.ajax({
                url: reviewurl,
                type: 'POST',
                // Pass the submitted form data to Controller
                data: form_data,
                success: function (response) {

                    var returnedData = JSON.parse(response);
                    if (returnedData.status === 'success')
                        $("#success").html(returnedData.messages);
                    else
                        $("#error").html(returnedData.messages);
                },
                error: function (response) {
                    var returnedData = JSON.parse(response);
                    $("#error").html(returnedData.messages);
                    a.closeModal();
                }
            });
            return false;
        });
    };
});

After you get success response you can simply a.modal("closeModal"); to close your modal.

For Example

success: function (response) {

    var returnedData = JSON.parse(response);
    if (returnedData.status === 'success')
        $("#success").html(returnedData.messages);
    else
        $("#error").html(returnedData.messages);

    a.modal("closeModal");
}
