[PATCH] tracing/fprobe: Call trace_probe_log_set_index(0) only once in __trace_fprobe_create()

[Markus Elfring <Markus.Elfring@web.de>]

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

A trace_probe_log_set_index(0) call was immediately used after a condition
check in this function implementation.
Thus call such a function only once instead directly before the check.

This issue was transformed by using the Coccinelle software.
