xfs: implement busy extent tracking for rtgroups
For rtgroups filesystems, track newly freed (rt) space through the log
until the rt EFIs have been committed to disk. This way we ensure that
space cannot be reused until all traces of the old owner are gone.
As a fringe benefit, we now support -o discard on the realtime device.
