Targetd Plugin: Fix vpd83 of targetd volume

* Target API only expose LVM UUID out. We have to convert it to VPD83 device
id using Linux LIO kernel way:
1. Prefix:
6 001405
- ------
^ ^
| |-- OpenFabric OUI [1]
|
|-- NAA IEEE Registered Extended DESIGNATOR 6h in T10 SPC 4 [2]

2. Extract all [a-f0-9A-F] from UUID out and convert to lower digits.
Example:
UUID: gQTwyb-PoV5-NxWw-gMn1-0u7X-2tGp-8iaV0A
^ ^ ^ ^ ^ ^ ^ ^ ^^
VPD 83 device ID(1h): 6001405b510728a0a000000000000000
^^^^^^^^^^
3. File up to 32 digits with zero.

Changes in V2(base on Andy Grover's suggest, many thanks to him):
1. Remove _lio prefix from method name.
2. Add detail explanation into code comments.
3. Remove 'if' check as `'0' * -1` will get a empty string.
