[FLINK-4894] [network] Don't request buffer after writing to partition
After emitting a record via the RecordWriter, we eagerly requested a new
buffer for the next emit on that channel (although it's not clear that we will
immediately need it). With this change, we request that buffer lazily when an
emit call requires it.
