LU-12488 tests: Fix sanityn 93 for DNE configs

sanityn test 93 only uses MDT0, but it is getting the parameter
qos_threshold_rr for all MDTs.  This confused the test when
trying to reset the parameter value.

Just limit everything to MDT0. Also modernize lctl vs
$LCTL usage and replace hardwired file system name with
$FSNAME.

Test-Parameters: trivial
Test-Parameters: testlist=sanityn
Test-Parameters: fstype=ldiskfs clientcount=2 mdscount=2 mdtcount=4 osscount=1 ostcount=8 testlist=sanityn
Test-Parameters: fstype=zfs clientcount=2 mdscount=2 mdtcount=4 osscount=1 ostcount=8 testlist=sanityn
