dcsctp: Track the number of inflight DATA items

This corresponds to one part of sstat_unackdata in RFC6458. The
remaining part is the data in the send queue, which isn't packetized
yet, so it must be estimated. But the DATA items in the retransmission
queue is already determined, so it can be easily tracked and retrieved.
