xfrm: set dst dev to blackhole_netdev instead of loopback_dev in ifdown
The global blackhole_netdev has replaced pernet loopback_dev to become the
one given to the object that holds an netdev when ifdown in many places of
ipv4 and ipv6 since commit 8d7017fd621d ("blackhole_netdev: use
blackhole_netdev to invalidate dst entries").
Especially after commit faab39f63c1f ("net: allow out-of-order netdev
unregistration"), it's no longer safe to use loopback_dev that may be
freed before other netdev.
This patch is to set dst dev to blackhole_netdev instead of loopback_dev
in ifdown.
v1->v2:
- add Fixes tag as Eric suggested.
Fixes: faab39f63c1f ("net: allow out-of-order netdev unregistration")
