xfs: get rid of the log item descriptor
It's just a connector between a transaction and a log item. There's a 1:1 relationship between a log item descriptor and a log item, and a 1:1 relationship between a log item descriptor and a transaction. Both relationships are created and terminated at the same time, so why do we even have the descriptor? Replace it with a specific list_head in the log item and a new log item dirtied flag to replace the XFS_LID_DIRTY flag.
