[Rivet] mixed up labels in CMS_2011_S9120041

Hi Emily,

Thus spake Emily Nurse (nurse at hep.ucl.ac.uk):

Thanks! I've cleaned up the analysis code now and fixed the labels.
Histograms are now only booked for the correct energy, and the code is
about 25% shorter than before ...

Cheers,

    Hendrik
