Subject: [PATCH net] openvswitch: properly refcount vport-vxlan module

After 614732eaa12d, no refcount is mainteined for the vport-vxlan module.
This allows the userspace to remove such module while vport-vxlan
devices still exist, which lead to later oops, i.e. when
the openvswitch module is removed.

Fixes: 614732eaa12d ("openvswitch: Use regular VXLAN net_device device")
