rtnetlink: fix VF info size
Commit1d8faf48c7
("net/core: Add VF link state control") added new attribute to IFLA_VF_INFO group in rtnl_fill_ifinfo but did not adjust size of the allocated memory in if_nlmsg_size/rtnl_vfinfo_size. As the result, we may trigger warnings in rtnl_getlink and similar functions when many VF links are enabled, as the information does not fit into the allocated skb. Fixes:1d8faf48c7
