dm: prepare for allocating blk-mq clone requests in target
For blk-mq request-based DM the responsibility of allocating a cloned
request will be transfered from DM core to the target type.
To prepare for conditionally using this new model the original
request's 'special' now points to the dm_rq_target_io because the
clone is allocated later in the block layer rather than in DM core.
