We've had reports in the past about this specific case, so it's time to go ahead and explicitly set cache_dynamic_acls=1 for generate_node_acls=1 (TPG demo-mode) operation. During normal generate_node_acls=0 operation with explicit NodeACLs -> se_node_acl memory is persistent to the configfs group located at /sys/kernel/config/target/$TARGETNAME/$TPGT/acls/$INITIATORNAME, so in the generate_node_acls=1 case we want the reservation logic to reference existing per initiator IQN se_node_acl memory (not to generate a new se_node_acl), so go ahead and always set cache_dynamic_acls=1 when TPG demo-mode is enabled.
