ni-utils: Fix DeviceCode value reported by fw_printenv
ni-utils: Fix DeviceCode value reported by fw_printenv

NI BIOSs inconsistently report DeviceCodes either with or
without a '0x' prefix. The required format that must be
reported is with a single '0x' prefix (e.g. 0xABCD).
This change adjusts malformed DeviceCode's to follow the
required format.
