MRP-856 utils: ext4lazyinit should be disabled

lazyinit need to finish more then 24H on typical OST installation
and produces writes inside read
we have a deadlock during shutdown with that feature enabled,
per OSG reports (OSG-766).

per testing, disabling that feature adds ~30 sec to formating OST
drive so that is not a noticeable time during install.
