ethtool: netlink: always pass genl_info to .prepare_data
We had a number of bugs in the past because developers forgot
to fully test dumps, which pass NULL as info to .prepare_data.
.prepare_data implementations would try to access info->extack
leading to a null-deref.
Now that dumps and notifications can access struct genl_info
we can pass it in, and remove the info null checks.
