LU-13751 tests: remove read of changelog sanity 160j

sanity test 160j tries to read the changelog after one of two
client mounts is unmounted.  In this case, we can fail to read
the changelog and get a "Cannot send after transport endpoint
shutdown" error.

The intention of sanity test 160j is to check that
there is no LBUG due to missed obd device.  So, do not try to
read from the changelog after file system unmount.
