lshw output is missing serial numbers for disks

[Jason Hobbs]

Here's the lshw xml output for my node:

Some disks, for example, /dev/sdd, don't have a serial number listed.

However, the serial number for the disk is available via udevadm:

So, it seems like lshw should be able to include the serial number too.

ubuntu 16.04
lshw 02.17-1.1ubuntu3.2
