[XFS] remove i_gen from incore inode
i_gen is incremented in directory operations when the directory is changed. It is never read or otherwise used so it should be removed to help reduce the size of the struct xfs_inode. The patch also removes a duplicate logging of the directory inode core. We only need to do this once per transaction so kill the one associated with the i_gen increment.
