Revert "rtnetlink: return EINVAL when request cannot succeed"
This reverts commit b6177d3240a4
ip-link command is testing kernel capability by sending a RTM_NEWLINK
request, without any argument. It accepts everything in reply, except
EOPNOTSUPP and EINVAL (functions iplink_have_newlink / accept_msg)
So we must keep compatiblity here, invalid empty message should not
return EINVAL
