Fix id in error when resource does not exist

Always set client->errorValue before returning an error.

Test program:

int main(int argc, char *argv[]) {
    int screen = 0;
    xcb_connection_t *c = xcb_connect(NULL, &screen);
    if (!c) {
        printf("Cannot connect\n");
        return 1;
    }

    xcb_void_cookie_t tok = xcb_free_gc_checked(c, BAD_VALUE);
    xcb_g_context_error_t *err = (xcb_g_context_error_t *)xcb_request_check(c, tok);
    if (!err) {
        printf("Unexpected request success\n");
        return 1;
    }
    if (err->bad_value != BAD_VALUE) {
        printf("Error: Got 0x%X, expected 0x%X\n", err->bad_value, BAD_VALUE);
        return 1;
    }
    printf("Success! Got expected bad value of 0x%X\n", BAD_VALUE);
    return 0;
}
