Subject: [PATCH] e2fsck: do not clean up file acl if the inode is truncating
 type

We got issue as follows:
    [root@localhost ~]# e2fsck -a img
    img: recovering journal
    img: Truncating orphaned inode 188 (uid=0, gid=0, mode=0100666, size=0)
    img: Truncating orphaned inode 174 (uid=0, gid=0, mode=0100666, size=0)
    img: clean, 484/128016 files, 118274/512000 blocks
    [root@localhost ~]# e2fsck -fn img
    e2fsck 1.46.5 (30-Dec-2021)
    Pass 1: Checking inodes, blocks, and sizes
    Inode 174, i_blocks is 2, should be 0.  Fix? no

Inode 188, i_blocks is 2, should be 0.  Fix? no

Pass 2: Checking directory structure
    Pass 3: Checking directory connectivity
    Pass 4: Checking reference counts
    Pass 5: Checking group summary information

img: ********** WARNING: Filesystem still has errors **********

img: 484/128016 files (24.6% non-contiguous), 118274/512000 blocks

File acl would be clean up in release_inode_blocks, whether the orphan
node is truncating or clearing type. If the inode is truncating type,
the file acl would be clean up, but the blocks count is not be
subtract acl blocks, and the inode is not unmark in bitmap, which causes
this issue.

To slove this issue, do not clean up file acl if the inode is truncating
type.
