[ext2fs] improve formatting speed

Browse source 
* Fix use of EXT2_BLOCK_SIZE() instead of EXT2_INODE_SIZE() during inode
  initialization, that made us zero way many more blocks than was needed.
* Also disable sparse_super feature and improve block setup.
* Also explicitly use IS_POWER_OF_2 macro where required.
