Dear Maintainer,

resolv.conf left configured after tunnel down due to lack of down script

While openvpn provides both:
https://github.com/OpenVPN/openvpn/tree/master/contrib/pull-resolv-conf

If you will be updating the current debian update-resolv-conf with
client.up / client.down from openwrt, please pay attention, that
client.up calls resolvconf with '-p' so it fails on debian.

I send patch to remove '-p', possibly the above note will become
obsolete.
