Bogus serial string in subiquity install wwn-eui.*

[Ryan Harper]

Curtin has been given (or maybe generated for subiquity) a storage config which includes a serial value with wwn prefixing the actual serial (eui-XXXXX). This results if failure to find the disk since the wwn prefix is not needed.

Curtin is prefixing 'wwn' for configs which specify a wwn value. The wwn value does not include the string 'wwn' and udev rules for persistent disks prefix the wwn with wwn-<WWN value).

However, for NVME, udev may export ID_WWN=eui.XXXX value, and it may well be a WWN, it does not get symlinked as a wwn-<WWN> symlink in /dev/disk/by-id at all.
