ocfs2: unlock inode if deleting inode from orphan fails

Browse Source 
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 cf1776a9e8 ("ocfs2: fix a tiny
race when truncate dio orohaned entry").
