SonarQube reveal two issues (could be refactored):

1. Delete this unreachable code or refactor the code to make it reachable (in both variants of validation crc/sha we have return statements):
   

   gitdb/gitdb/pack.py

   Line 851 inf8fdfec

   returnTrue

2. This branch duplicates the one on line 268.
   

   gitdb/gitdb/pack.py

   Line 270 inf8fdfec

   elifattr=="_packfile_checksum":

   
   and
   

   gitdb/gitdb/pack.py

   Line 268 inf8fdfec

   ifattr=="_packfile_checksum":
