This patch adds the default 'Unrestricted reordering allowed' for SCSI control mode page QUEUE ALGORITHM MODIFIER on a per se_device basis in target_modesense_control() following spc4r23. This includes a new emuluate_rest_reord configfs attribute that currently (only) accepts zero to signal 'Unrestricted reordering allowed' in control mode page usage by the backend target device.
