vxlan: fix use-after-free on deletion
Adding a vxlan interface to a socket isn't symmetrical, while adding
is done in vxlan_open() the deletion is done in vxlan_dellink().
This can cause a use-after-free error when we close the vxlan
interface before deleting it.
We add vxlan_vs_del_dev() to match vxlan_vs_add_dev() and call
it from vxlan_stop() to match the call from vxlan_open().
Fixes: 56ef9c909b40 ("vxlan: Move socket initialization to within rtnl scope")
