bcachefs: New erasure coding shutdown path
This implements a new shutdown path for erasure coding, which is needed for the upcoming BCH_WRITE_WAIT_FOR_EC write path. The process is: - Cancel new stripes being built up - Close out/cancel open buckets on write points or the partial list that are for stripes - Shutdown rebalance/copygc - Then wait for in flight new stripes to finish With BCH_WRITE_WAIT_FOR_EC, move ops will be waiting on stripes to fill up before they complete; the new ec shutdown path is needed for shutting down copygc/rebalance without deadlocking.
