Subject[PATCH 1/4 V2] ocfs2: use retval instead of status for checking error
The use of 'status' in __ocfs2_add_entry() can return wrong
status when some functions are failed.

If ocfs2_journal_access_db() in __ocfs2_add_entry() is failed,
that status is saved to 'status' but return variable is 'retval'
which is saved 'success' status. In case of this, __ocfs2_add_entry()
is failed but can be returned as 'success'.

So replace 'status' with 'retval'.
