Under heavy metadata load, metadata passes can monopolize the write budget every cycle while data passes get nothing written. Track consecutive monopolized cycles per device in l2ad_meta_cycles. After l2arc_meta_cycles (default 2) consecutive cycles where metadata fills the write budget, skip metadata for one cycle to let data run. Reset the counter when nothing is written.
