Subject: ocfs2: fix remounting needed after setfacl command

When use setfacl command to change a file's acl, the user cannot get the
latest acl information from the file via getfacl command, until remounting
the file system.

setfacl -m u:ivan:rw /ocfs2/ivan
getfacl /ocfs2/ivan
getfacl: Removing leading '/' from absolute path names
file: ocfs2/ivan
owner: root
group: root

The latest acl record("u:ivan:rw") cannot be returned via getfacl
command until remounting.
