libquota: fix quota_inode_truncate()
We failed to clear EXT2_FLAG_SUPER_ONLY after deleting the
quota inode and so, the updated block bitmap was not written
back. This caused fsck to complain after running
'tune2fs -O ^quota <dev>'. Clear this flag so that updated
block bitmap gets written. Also, avoid truncating the quota
inode if it is not hidden.
