Subject: skbuff: make skb_put_zero() return void
Patch-mainline: v4.13-rc1
Git-commit: 83ad357dee467f63574de35752bc40033deab30e
References: bsc#1056787

It's nicer to return void, since then there's no need to
cast to any structures. Currently none of the users have
a cast, but a number of future conversions do.
