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.
