mpls: Properly validate RTA_VIA payload length
If the nla length is less than 2 then the nla data could be accessed beyond the accessible bounds. So ensure that the nla is big enough to at least read the via_family before doing so. Replace magic value of 2. Fixes: 03c0566542f4 ("mpls: Basic support for adding and removing routes") Cc: Eric W.
