Subject: [PATCH 1/2] scsi: Add missing SPC-4 CDB and MAINTENANCE_[IN,OUT] and VARIABLE_LENGTH_CMD service actions

From: Nicholas Bellinger <nab@...ux-iscsi.org>

This patch adds a handful of missing CDBs defs that are used by TCM
persistent reservation logic in the SPC-4 defined CDB exclusion table for
registrations and reservations.

This includes a number of missing MI_* and MO_* prefixed service actions defs
for MAINTENANCE_IN and MAINTENANCE_OUT that are mentioned wrt to persistent
registration and reservation status for the SCSI Initiator Port.

Finally it adds the remaining missing VARIABLE_LENGTH_CMD service actions
XDREAD_32, XDWRITE_32, XPWRITE_32 and XDWRITEREAD_32.
