ocfs2: add ocfs2_init_security in during file create
Security attributes must be set when creating a new inode.
We do this in three steps.
- First, get security xattr's name and value by security_operation
- Calculate and reserve the meta data and clusters needed by this security
xattr before starting transaction
- Finally, we set it before add_entry
