ocfs2: use retval instead of status for checking error
The use of 'status' in __ocfs2_add_entry() can return wrong value.
Some functions' return value in __ocfs2_add_entry(), i.e
ocfs2_journal_access_di() is saved to 'status'. But 'status' is not
used in 'bail' label for returning result of __ocfs2_add_entry().
So use retval instead of status.
