Subject: [PATCH] Use same serial num in getconfig:unitserialnum as inquiry does
The feature GetConfiguration/Lun_Serial_Number is used to pull
the unit serial number from a device.
Use the same data that inq 0x80 uses to report the serial number
so that both methods (getconf and inq) report the same serial number
for the device.
