qa: Disable referent inodes for a few test_strays tests

It's disabled for following tests

 test_hardlink_reintegration
 test_mv_hardlink_cleanup

The stray perf count numbers validation in above tests don't match
with referent inodes enabled because referent inodes becomes a stray
whenever hardlink is deleted or stray is reintegrated, so disable
referent inodes. The same test for referent inodes is added at
qa/tasks/cephfs/test_referent.py adjusting the perf counters for
referent inodes.
