Kir Kolyshkin 9b0097a699 Format code with gofmt -s from go-1.11beta1
This should eliminate a bunch of new (go-1.11 related) validation
errors telling that the code is not formatted with `gofmt -s`.

No functional change, just whitespace (i.e.
`git show --ignore-space-change` shows nothing).

Patch generated with:

> git ls-files | grep -v ^vendor/ | grep .go$ | xargs gofmt -s -w
