Subject: [PATCH nf-next] net-ipvs: Delete an unnecessary check before the function call "module_put"

From: Markus Elfring <elfring@...rs.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.
