Markus Elfring 982f405136 netfilter: Deletion of unnecessary checks before two function calls ...

The functions free_percpu() and module_put() test whether their argument
is NULL and then return immediately. Thus the test around the call is
not needed.

This issue was detected by using the Coccinelle software.
