Drivers: hv: vmbus: Negotiate version 3.0 when running on ws2012r2 hosts

commit 03367ef5

 upstream.

Only ws2012r2 hosts support the ability to reconnect to the host on VMBUS.
This functionality is needed by kexec in Linux. To use this functionality
we need to negotiate version 3.0 of the VMBUS protocol.

This patch has been backported to apply against the 3.12 stable tree.
