Added support for kernel 4.6

If vrouter is building for 4.6 new API should be used instead.

I have some other compile errors with kernel >=4.6 (kernel 4.9.49) and it is strange you didn't get them...

First, skb_sender_cpu_clear has been removed in kernel 4.6:

Fix build for kernels >= 4.9

- skb_sender_cpu_clear has been removed in kernel 4.6 [1] and is no longer
required since 4.5 [2].

- get_user_page signature has changed in 4.6 [3] and in 4.9 [4]. Since I
don't have a 4.6 kernel for testing, I didn't add code to support it.

- The macro page_cache_release has been finally removed [5].

Summary of discussions with Jeba

=======

1633387 – W.r.t. Ubuntu, we need to make sure vrouter.ko is DKMS compatible against any kernel. When 4.x kernel came to market long back, we observed that vrouter does not DKMS compile against that kernel and the bug was filed. However at that time our customers were in 3.x kernels. Recently there are use-cases forced us to fix this and as per my understanding, this is fixed by the commits made already. We will keep it in 5.0.2 scope and close it after assessing all use-case. Mainly AWS, Azure, GCP, vR-vR encryption needs latest kernels.
