Pending block replication can get stuck using older genstamp

      Description

      If an under-replicated block gets into the pending-replication list, but later the genstamp of that block ends up being newer than the one originally submitted for replication, the block will fail replication until the NN is restarted.

      It will be safer if processPendingReplications() gets up-to-date blockinfo before resubmitting replication work.
