tools/libxl: cleanup one libxl__calloc() usage

Its pointless because internally, libxl__calloc() would always
terminate program execution if failed,

libxl__calloc()
    |
    + void *ptr = calloc(nmemb, size);
    + if (!ptr) libxl__alloc_failed(CTX, __func__, nmemb, size);
                    |
                    + _exit(-1);
