 * 5.6.5.1
 * New PG objects are registered when an associated Portal or

 * registration MAY follow a Portal or iSCSI Node object
 * registration in a DevAttrReg message.
 * [...]
 * If the PGT value is not included in the Storage Node or
 * Portal object registration, and if a PGT value was not
 * previously registered for the relationship, then the PGT for
 * the corresponding PG object SHALL be registered with a value
 * of 0x00000001.
 *
 * We return non-NULL if the object was created.
