Description

We see sanity test_27D subtest 34 fail for interop testing between master (2.13.0) and latest 2.12 with the following from the client test_log

test 32: Test overstriping with layout_file_create ....................................... skip
 test 33: Test overstriping with llapi_file_open .......................................... skip
Invalid layout: No adjacent extension space components
llapi_layout_test: llapi_layout_test.c:1729: test34: assertion 'fd >= 0' failed: path = /mnt/lustre/d27D.sanity/f34, fd = -1, errno = 22
 test 34: create simple valid & invalid self extending layouts ............................ fail (exit status 1)
 sanity test_27D: @@@@@@ FAIL: llapi_layout_test failed 
  Trace dump:
  = /usr/lib64/lustre/tests/test-framework.sh:6115:error()
  = /usr/lib64/lustre/tests/sanity.sh:2481:test_27D()

The issue looks like patch https://review.whamcloud.com/33784 for LU-10070 added sanity test 27D subtest 34, but added a test in sanity to skip test 32 if the MDS was less than $SEL_VER which is 2.12.52 which should probably be 2.12.56. I think subtest 34 should be skipped and not test 32.
