Sync of ACL with std permissions fail，We need to forget the ACL cache after setattr.
Reproduction:
#!/bin/bash
touch testfile
cat <<EOF >testfile
#!/bin/bash
echo "Test was executed"
EOF
chmod u=rwx testfile
chmod g=rw- testfile
chmod o=r-- testfile
chacl u::r--,g::rwx,o:rw- testfile
chmod u+w testfile
ls -l testfile
chacl -l testfile
Output：
-rw-rwxrw- 1 root root 0 Mar 28 05:29 testfile
testfile [u::r--,g::rwx,o::rw-]
