procd: May hangs during reboot because of netdevice reference counter imbalance

Device problem occurs on: Basically all I’ve tested (ar71xx, ipq806x, ipq40xx, ...)
-
Software versions of OpenWrt/LEDE: LEDE 17.01x
-
Steps to reproduce: Install the attached package, boot the system, try to reboot it
It was observed that OpenWrt sometimes prints
unregister_netdevice: waiting for br-lan to become free. Usage count = 1
and then hangs indefinitely when trying to reboot. Doing a hard reset seems to the the only way to resolve this problem.
I didn’t have such problems with a systemd based Debian Stretch system and the same trigger kernel module
