[#LU-10600] sanity test 66 hangs when run after tests 64d and 65k

The above commands with set up Lustre with one combined MGS/MDS and two OSTs with loop back devices on a single node. The auster command will run sanity test 64d, 65k and 66 only.

== sanity test 66: update inode blocks count on client =============================================== 19:11:04 (1517512264)

Looking at the testing output, we see that test 64d fills an OST and doesn’t remove the file and then test 65k deactivates one OST at a time and, when it has deactivated the empty OST and tries to use the full one, the ‘lfs setstripe’ command fails. Test 65k exits when the ‘lfs setstripe’ command fail and leaves one OST deactivated.

 [797721.192593] Lustre: DEBUG MARKER: == sanity test 66: update inode blocks count on client =============================================== 23:33:24 (1517614404)

We need to clean up the file from test 64d and, on failure, we need to activate the OST and clean up files in test 65k.
