Gorka Eguileor f80fcd0e7a SCSI: Support non SAM LUN addressing
This patch adds non SAM addressing modes for LUNs, specifically for
SAM-2 and SAM-3 flat addressing.

Code has been manually verified on Pure storage systems that uses SAM-2
addressing mode, because it's unusual for CI jobs to have more than
256 LUNs on a single target.

Closes-Bug: #2006960
Change-Id: If32d054e8f944f162bdc8700d842134a80049877
