[PATCH] perf probe: Delete an unnecessary check before the function call "strfilter__delete"

[SF Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sat, 4 Jul 2015 07:44:22 +0200

The strfilter__delete() 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.
