This patch defers the queue policy to the VF so that all the queues can be used. This impacts workloads like local generate UDP.

From: Simon Xiao <sixiao@microsoft.com>

Please close this PR, as I made PR #20, which includes the first commit of this PR.

The second patch (Drivers: hv: vmbus: assign CPU to channel in a Hyper-Threading awareness way) in t his PR is not needed, according to Simon Xiao.
