ocfs2: implement ocfs2_direct_IO_write

Implement ocfs2_direct_IO_write.  Add the inode to orphan dir first, and
then delete it once append O_DIRECT finished.

This is to make sure block allocation and inode size are consistent.

[akpm@linux-foundation.org: fix it for "block: Add discard flag to blkdev_issue_zeroout() function"]
