sanity test_27D fails when a default composite layout is set for the Lustre mount point with

sanity test_27D: @@@@@@ FAIL: llapi_layout_test failed

Looking at the test_log, we can see that sub tests 16 and 20 failed

test 15: Can't change striping attributes of existing file . pass
llapi_layout_test: llapi_layout_test.c:712: test16: assertion 'fcount == dcount' failed: 1 != 1152921504606846979
 test 16: Default stripe attributes are applied as expected . fail (exit status 1)
 test 17: LLAPI_LAYOUT_WIDE is honored ...................... pass
 test 18: Setting pool with fsname.pool notation ............ pass
 test 19: Maximum length pool name is NULL-terminated ....... pass
llapi_layout_test: llapi_layout_test.c:891: test20: assertion 'fcount == dcount' failed: 1 != 1152921504606846979
 test 20: LLAPI_LAYOUT_DEFAULT is honored ................... fail (exit status 1)

Looking at llapi_layout_test.c, it looks like the stripe count for the default layout does not match the count for the file layout

 692         rc = llapi_layout_stripe_count_get(deflayout, &dcount);
 693         ASSERTF(rc == 0, "errno = %d", errno);
 694 
 695         /* First, with a default struct llapi_layout */
 696         filelayout = llapi_layout_alloc();
 697         ASSERTF(filelayout != NULL, "errno = %d", errno);
 698 
 699         fd = llapi_layout_file_create(path, 0, 0640, filelayout);
 700         ASSERTF(fd >= 0, "errno = %d", errno);
 701 
 702         rc = close(fd);
 703         ASSERTF(rc == 0, "errno = %d", errno);
 704 
 705         llapi_layout_free(filelayout);
 706 
 707         filelayout = llapi_layout_get_by_path(path, 0);
 708         ASSERTF(filelayout != NULL, "errno = %d", errno);
 709 
 710         rc = llapi_layout_stripe_count_get(filelayout, &fcount);
 711         ASSERTF(rc == 0, "errno = %d", errno);
 712         ASSERTF(fcount == dcount, "%"PRIu64" != %"PRIu64, fcount, dcount);
