netdev: let netlink core handle -EMSGSIZE errors
Previous change added -EMSGSIZE handling to af_netlink, we don't
have to hide these errors any longer.
Theoretically the error handling changes from:
if (err == -EMSGSIZE)
to
if (err == -EMSGSIZE && skb->len)
everywhere, but in practice it doesn't matter.
All messages fit into NLMSG_GOODSIZE, so overflow of an empty
skb cannot happen.
