[PATCH 09/11] perf probe: Delete an unnecessary check before the function call "strfilter__delete"

[Arnaldo Carvalho de Melo <acme@kernel.org>]

From: Markus Elfring <elfring@users.sourceforge.net>

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.
