[illumos-Developer] Review for #429 iostat -E does not report serial number

[Garrett D'Amore]

Right, page 80, and 83, can be used to obtain a globally unique id for
most drives (all SAS and FC drives at least).  Whether this is precisely
the device's "serial number" is not guaranteed.  But its the best we can
do with the nebulous state of the SCSI specs for this.
