    This patch contains the squashed version of second round of target core
    cleanups and simplifications and Andy and Co.   It also contains a handful
    of fixes to address bugs the original series and other minor cleanups.
    
    Here is the condensed shortlog:
    
    target: Remove unneeded casts to void*
    target: Rename get_lun_for_{cmd,tmr} to lookup_{cmd,tmr}_lun
    target: Make t_task a member of se_cmd, not a pointer
    target: Handle functions returning "-2"
    target: Use cmd->se_dev over cmd->se_lun->lun_se_dev
    target: Embed qr in struct se_cmd
    target: Replace embedded struct se_queue_req with a list_head
    target: Rename list_heads that are nodes in struct se_cmd to "*_node"
    target: Fold transport_device_setup_cmd() into lookup_{tmr,cmd}_lun()
    target: Make t_mem_list and t_mem_list_bidi members of t_task
    target: Add comment & cleanup transport_map_sg_to_mem()
    target: Remove unneeded checks in transport_free_pages()
    
    (Roland: Fix se_queue_req removal leftovers OOPs)
    (nab: Fix transport_lookup_tmr_lun failure case)
    (nab: Fix list_empty(&cmd->t_task.t_mem_bidi_list) inversion bugs)
