Subject: ocfs2: unlock inode if deleting inode from orphan fails
When doing append direct io cleanup, if deleting inode fails, it goes out
without unlocking inode, which will cause the inode deadlock. This issue
was introduced by commit cf1776a9e834("ocfs2: fix a tiny race when
truncate dio orohaned entry").
