Subject: [PATCH 1/2] vxlan: remove vxlan_group_used in vxlan_open

In vxlan_open, vxlan_group_used always returns true,
because the state of the vxlan deivces which we want
to open has alreay been running. and it has already
in vxlan_list.

Since ip_mc_join_group takes care of the reference
problem. we can remove vxlan_group_used here, let
ip_mc_join_group resolve the reference problem.
