setup/fs: fix ext4 lazyinit performance issue

During ext4 filesystem performance test, we find newly formatted ext4 fs will create
a lazyinit kernel thread in background, which will disturb fio performance test.
According to https://www.thomas-krenn.com/en/wiki/Ext4_Filesystem#Lazy_Initialization,
it is better to disable lazyinit mechanism to make ext4 performance test result similar
to workload in realworld.
For ext2, there is no lazyinit mechanism, so the format parameters for ext2 remain as before.
