Okay.

Well, the return 0; is there just to silent compiler as cleanup() calls
tst_exit(); The best solution is IMHO add noreturn attribute to
cleanup() and remove the return 0;

Checking it doesn't do any harm. ;)

As far as I understand the tests, changing permissions on tmp directory
is not needed as the test is testing permissions on symlinks created
inside of it (so we only need that the content of the directory is
accesible). I susspect that this is some workaround that wasn't removed
when test was ported for LTP.
