Edward Tomasz Napierala deda5987bc With NFSv4 ACLs, it is possible that applying a mode to an ACL which 
is identical to the mode computed from that ACL will modify the ACL.
For example, mode computed from the following ACL is 0600:

   user:kamila:rwx--------C--:------:allow
        owner@:--x-----------:------:deny
        owner@:rw-p---A-W-Co-:------:allow
        group@:rwxp----------:------:deny
        group@:--------------:------:allow
     everyone@:rwxp---A-W-Co-:------:deny
     everyone@:------a-R-c--s:------:allow

However, applying that mode (chmod 0600) changes the ACL into this:

   user:kamila:rwx-----------:------:deny
   user:kamila:rwx--------C--:------:allow
        owner@:--x-----------:------:deny
        owner@:rw-p---A-W-Co-:------:allow
        group@:rwxp----------:------:deny
        group@:--------------:------:allow
     everyone@:rwxp---A-W-Co-:------:deny
     everyone@:------a-R-c--s:------:allow

In chmod(1) utility, there is an optimisation, which makes it not
call chmod(2) if the mode of the file is the same as the new mode.
Disable that optimisation for files which may have NFSv4 ACLs.
