`bucket_send()` and `bucket_recv()` should check `rebalancer_transfering_buckets` before touching it #434

Closed Gerold103 closed 1 year ago

bucket_send(bid) sets M.rebalancer_transfering_buckets[bid] = true without checking if it was already true. 1) Need to check it and fail immediately if the bucket is in transfer already. 2) See if the current behaviour can lead to any bugs. Cover them with tests.

Same with bucket_recv().
