cleanup uninitialized reads or conditions and leaks

[slava77]

these were collected from the valgrind report for "step3" run with a 2017 workflow with PU (10211).

The change in DQM/SiPixelPhase1Common/interface/GeometryInterface.h actually didn't fix anything, but it still looks useful.

Local short matrix run shows no differences.

for #19426 ff0e38f

• jenkins tests pass and comparisons show no differences in reco and one (expected) change in ECAL DQM

this histogram now shows properly values per event (compared to a cumulative value summing over all events, with occasionally uninitialized initial value)
