commit 71c93c89064c3c9fcdba4a2731c9287fb72bd8a2
Author: Prabhjot Singh Sethi <email address hidden>
Date: Sat Feb 21 05:52:42 2015 -0800

Fixing uninitialised variables in Logical Switch

Issue:
------
In one Logical switch constructor mcast row pointers were not
initialised, due to which on access results in segmentation
fault.

Fix:
----
initialising ovs mcast row pointer in constructor.
