PR description:

PR to fix the bug in HLTMuonDimuonL3filter.cc
The module allows selection of separate mass windows for dimuon candidates,
but only the first mass window is considered because of the bug.
This affects for instance the HLT path HLT_DoubleMu4_LowMassNonResonantTrk_Displaced,
using [1.0, 2.9] U [4.0, 4.8]
Events in the windows other than the first are now considered

PR validation:

A trigger path for non resonant dimuons has been used for test
(config file: /afs/cern.ch/user/v/vmastrap/public/fix-dimu-mass-windows/hlt.py)
and run on EphemeralHLTPhysics dataset
(file list: /afs/cern.ch/user/v/vmastrap/public/fix-dimu-mass-windows/list_cff.py)
Events in the second mass window fire the trigger after the bug fix
(plot: /afs/cern.ch/user/v/vmastrap/public/fix-dimu-mass-windows/plot.pdf)

The filter in question could use a cleanup to at least improve code readibility.
Otoh, I prefer not to delay the integration of this bugfix for purely technical changes (the latter could be done in a future PR).

This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @perrotta, @dpiparo, @qliphy (and backports should be raised in the release meeting by the corresponding L2)
