[PATCH] net: sched: skip an unnecessay check

From: trix
Date: Mon Sep 07 2020 - 14:05:46 EST


From: Tom Rix <trix@xxxxxxxxxx>

Reviewing the error handling in tcf_action_init_1()
most of the early handling uses

err_out:
if (cookie) {
kfree(cookie->data);
kfree(cookie);
}

before cookie could ever be set.

So skip the unnecessay check.
