The commit ac0b04627269ff16c3c7ab854a65fe6780c6e3e5 has added
an item of SctpInDataChunkDiscards for tracing discarded DATA chunk
with high tsn, bad stream or dup tsn at ESTABLISHED state.
But at SHUTDOWN-SENT state, this kind of discarded DATA chunk
can't be traced. So increase the counter value of SctpInDataChunkDiscards
for them.
