Christoph Hellwig 83bac569c7 xfs: prevent gc from picking the same zone twice ... When we are picking a zone for gc it might already be in the pipeline which can lead to us moving the same data twice resulting in in write amplification and a very unfortunate case where we keep on garbage collecting the zone we just filled with migrated data stopping all forward progress. Fix this by introducing a count of on-going GC operations on a zone, and skip any zone with ongoing GC when picking a new victim.
