The support for trailing DRAM lines was broken. This patch starts
rework of support for this, but in order to do that, we need to
rework decode_chunk_ts() a little first.

This patch adjusts the decode_chunk_ts() a little to receive the
total amount of events in DRAM line instead of some nonsense value.
This patch temporarily removes the support for the trailing DRAM
lines until the decode_chunk_ts() is fixed to cope with this, so
yes, this patch introduces breakage!
