xfs: add a realtime flag to the bmap update log redo items

Source kernel commit: 7302cda7f8b08062b11d2ba9ae0b4f3871fe3d46

Extend the bmap update (BUI) log items with a new realtime flag that
indicates that the updates apply against a realtime file's data fork.
We'll wire up the actual code later.
