Fix nasty bug with decoding single ROC DESER160 data, introduced
by f7d74ba1293104436610a7ae07e98f375825392a : with not stripping
the identifier bist when splitting, we need to discard them while
decoding. This makes more sense in general since we are preserving
all data without eating up more resources.
