Added fix for IB core

From: Ilya Nelkenbaum <ilyan@mellanox.com>
Subject: [PATCH] IB/core: When marshaling ucma path from user-space,
clear unused fields

When marsheling a user path to the kernel struct ib_sa_path, need
to zero smac, dmac and set the vlan id to the "no vlan" value.

This is to ensure that Ethernet attributes are not used with
InfiniBand QPs.

Fixes: dd5f03beb4f7 ("IB/core: Ethernet L2 attributes in verbs/cm
structures")
