[PATCH 2/4] perf probe: Delete an unnecessary assignment in try_to_find_absolute_address()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Mon, 23 Jan 2017 15:10:19 +0100

Remove an error code assignment which is redundant in an if branch for
the handling of a memory allocation failure because the same value was set
for the local variable "err" before.
