fa7991601c Fixup style of VerifyDB (MarcoFalke)
fa462ea787 Avoid implicit-integer-sign-change in VerifyLoadedChainstate (MarcoFalke)

Pull request description:

  This happens when checking all blocks (`-1`).

  To test:

  ```
  ./configure CC=clang CXX=clang++ --with-sanitizers=undefined,integer
  make
  UBSAN_OPTIONS="suppressions=$(pwd)/test/sanitizer_suppressions/ubsan:print_stacktrace=1:halt_on_error=1:report_error_type=1" ./test/functional/rpc_blockchain.py
