I suggest that err variable should be completely removed. Could you
please also do the same thing for this code ?

err = skb_handler(skb, cb, tsk);
if (err) {

If we write the code as:

if (some_function(parameters)) {

then at first that looks like a boolean. People probably think the
function returns true/false. But if we leave it as-is:

err = some_function(parameters);
if (err) {

Then that looks like error handling.

So it's better and more readable to leave it as-is.

I concur with Dan's comments.
