mgr/telemetry: fix device id splitting when anonymizing serial
Anonymizing the serial number in the device id string fails in rare
cases where 'vendor' and 'model' are missing from the device id
string. Ideally, device id is generated (in blkdev.cc) as
'vendor_model_serial', in case all fields were successfully retrieved
from the device. In cases where they were not, device id can also be
generated as 'model_serial' or 'serial'. Splitting by '_' fails in the
latter case (since 'serial' is the only element in the string).
In order to anonymize serial numbers in smartctl reports we now rely
on the serial number value as retrieved from the raw smartctl report
itself (as opposed to the one in device id). That's in order to avoid
possible inconsistencies between the serial retrieved from device id and
the one in the report.
