Small modifications:

1.) debug streamer had to be explicitly open in recreate mode
2.) default values of correction factors HVandPT (1 instead of 0)

M       Rec/AliTPCtracker.cxx              - Debug streamer open in the recreate mode
M       Rec/AliTPCclusterer.cxx            - Debug streamer only in case of given bitmask active
M       Rec/AliTPCseed.cxx                 - Protection against 0 per chamber calibration
M       Base/AliTPCcalibDB.cxx             - Default value for the HVandPT correction is 1 as it is multiplicative correction factor
