Fixing minor error in Scouting DQM module

[jprendi]

PR description:

@mmusich noticed an error in the way the primaryVertex_counter is initialised within the code. The way it was until now, the counter does to not get updated for each event separately. The fix starts and sets the counter to 0 each over each event.

PR validation:

Using input files set at cms-data/DQM-Integration#12 by coping inside the DQM/Integration/data/run392642 folder and running:

cmsRun DQM/Integration/python/clients/scouting_dqm_sourceclient-live_cfg.py runInputDir=DQM/Integration/data/ runNumber=392642 scanOnce=True

followed by subsequent inspection of the output histograms.

If this PR is a backport please specify the original PR and why you need to backport that PR. If this PR will be backported please specify to which release cycle the backport is meant for:

Not a backport, but it will be backported to CMSSW_15_0_X for data-taking operations.
