Subject: [PATCH net-next 2/6] selftests: forwarding: multipath_eval(): Improve
 style

- Change the indentation of the function body from 7 spaces to one tab.
- Move initialization of weights_ratio up so that it can be referenced
  from the error message about packet difference being zero.
- Move |'s consistently to continuation line, which reindent.
