ocfs2: unlock inode if deleting inode from orphan fails
commit a4a8481ff68a8a324a878e281bc37f18665224f7 upstream.
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").
