Anton Protopopov b7384eab87 libbpf: Use proper errno value in nlattr 
[ Upstream commit fd5fd538a1 ]

Return value of the validate_nla() function can be propagated all the
way up to users of libbpf API. In case of error this libbpf version
of validate_nla returns -1 which will be seen as -EPERM from user's
point of view. Instead, return a more reasonable -EINVAL.

Fixes: bbf48c18ee ("libbpf: add error reporting in XDP")
