Subject: [PATCH] device_id: fix segfault verifying serial for non-pv
The recent change that verifies sys_serial system.devices entries
using the PVID did not exclude non-PV devices from being checked.
The verification code would attempt to use du->pvid which was null
for the non-PVs causing a segfault.
(cherry picked from commit 6613a61d3b5ce4d12a6fef79195eac34f30ef4da)
