[PATCH] add scsi_level and revision support to lsscsci 0.03

[Patrick Mansfield <patmans@us.ibm.com>]

Doug -

This patch adds support for use of scsi_level and the output of revision
to lsscsi 0.03. It should work even without scsi_level in the scsi sysfs
attributes.

lsscsi -c now gives the exact same output as catting /proc/scsi/scsi.
