Currently e2fsck always incorrectly detects that quota inodes need to be hidden (even if they are already hidden) and modifies the superblock unnecessarily. This patch fixes the check for hidden quota files and avoids modifying the filesystem if quota inodes are already hidden. Also, zero-out the old quota inode so that next fsck scan doesn't complain.
