xfs: push perags through the ag reservation callouts
We currently pass an agno from the AG reservation functions to the individual feature accounting functions, which in future may have to do perag lookups to access per-AG state. Instead, pre-emptively plumb the perag through from the highest AG reservation layer to the feature callouts so they won't have to look it up again.
