When there is only one bridge,create tunnel in the bridge,
then delete the bridge directly. the system tunnel interface
still in.
Cause of only one bridge, backer->refcount values 1, when
delete bridge, "close_dpif_backer" will delete the backer,
so type_run will return directly, doesn't delete the interface.
This patch delete the system interface before free the backer.
Fixes: 921c370a9df5 ("dpif-netlink: Probe for out-of-tree tunnels, decides used
interface")
