This patch mostly is related to tunnel API where RHEL 7
kernel API are not in-sync with newer linux kernel API. So
extra checks are required to check for parameters of API.

vxlan-udp-recv function lookup vxlan_sock struct on every packet
recv by using udp-port number. we can use sk->sk_user_data to
store vxlan_sock and avoid lookup.
This commit also allows us to get rid of socket hash table.

To use ovs-gso-compatibility we need to record inner skb offset.
In case of vxlan it is done before vlan header is pushed which
gives wrong inner packet to ovs-gso.
Following patch reset skb offsets after inner skb is completely built.

OVS has its own workq implementation for coupe of reasons. first
was to avoid system freeze due to ovs-flow rehash softlockup.
We have moved out rehash from workq, So this problem does not exist.
second was related bugs in kernel workq implementation in pre-2.6.32
kernel. But we have dropped support for older kernel.
So there is no reason to keep ovs-workq around. Following patch
removes it.
