netlink: Delete an unnecessary check before the function call « module_put »
Author: Markus Elfring <elfring@users.sourceforge.net>
The module_put() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.
