device_id: handle duplicate serial numbers Handle multiple devices using the same serial number as their device id. After matching devices to devices file entries, if there is a discrepency between the ondisk PVID and the devices file PVID, then rematch devices to devices file entries using PVID, looking at all disks on the system with the same serial number.

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.

device_id: handle duplicate serial numbers Handle multiple devices using the same serial number as their device id. After matching devices to devices file entries, if there is a discrepency between the ondisk PVID and the devices file PVID, then rematch devices to devices file entries using PVID, looking at all disks on the system with the same serial number.
