We are doing ext2fs_flush() twice right now at the end of the mke2fs. First by directly calling ext2fs_flush() which is intended to write superblock and fs accounting information. And then it is invoked again when we are calling ext2fs_close(), only this time, because the fs is not dirty, we are writing out only superblock. I think it is bad to call it twice because even when writing only super block it takes some time on bigger file systems and moreover ext2fs_close() can fail without any reasonable explanation for the user. Also ext2fs_flush() is printing out progress and it is confusing for the users. Fix all this by removing the ext2fs_flush() and leaving it all to ext2fs_close(). However we need to introduce new variables to store check interval and max mount count, because fs structure is freed on ext2fs_close() and we really want to print those information as the last info for the user.
