osd: give deletion ops a cost when performing backfill
Pull request ID:
From PrimaryLogPG, line 11134 (at time of writing)
// Don't increment ops here because deletions // are cheap and not replied to unlike real recovery_ops, // and we can't increment ops without requeueing ourself // for recovery.
That is, we assume removing objects is free when budgeting our backfill ops. Stop doing that.
