suppress LogError for somewhat clearly bad input of TrajectoryStateCombiner (backport of #15016)

[slava77]

[copy-pasted message from #15016]
demote TrajectoryStateCombiner::combiner MatrixInversionFailure issue to LogWarning for all and issue no message for somewhat clearly bad inputs.

Fairly frequent LogErrors from MatrixInversionFailure category in module StandAloneMuonProducer:standAloneSETMuons

In my test I re-recoed about 5K events from Run2016B/MET/RAW-RECO/LogError-PromptReco-v2 runs (fractionally) 274241,274244,274250,274251,274282 for a total of 166 LS.

This error happened 641 times (some repeated multiple times in event)
and all of the cases were for a transformation of a seed with TSOS with 0 error values in in q/p row/column. This is clearly not invertible.

Maybe in the long run there should be a change in logic of the algorithm.

• jenkins tests pass and show no differences (the affected logErrors are not frequent enough to show up in the tests)

This pull request is fully signed and it will be integrated in one of the next CMSSW_8_0_X IBs (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @slava77, @davidlange6, @Degano, @smuzaffar
