[PATCH] iproute2: 0 out memory for tc_skbedit struct prior to using it.

[Jeff Kirsher <jeffrey.t.kirsher@intel.com>]

From: Alexander Duyck <alexander.h.duyck@intel.com>

A bug was found in which the memory for the tc_skbedit struct was being
used uninitialized to 0.  This patch corrects the issue by using a memset
to 0 out the memory of the structure.
