LU-17146 tests: avoid sanity-lfsck/test_38 failure

This regression has been introduced in kernels after commit
v5.11-10234-gcbd59c48ae2b (5.12), and is fixed with
commit v6.2-rc4-61-g5956592ce337 (6.2).
The issue has been introduced by upstream
commit 8c8387ee3f55
("mm: stop filemap_read() from grabbing a superfluous page").
Skip sanity-lfsck/test_38 for this range of kernels.
