target: ->map_task_SG conversion to ->map_control_SG and ->map_data_SG
This patch breaks up the ->map_task_SG() backend call into two seperate
->map_control_SG() and ->map_data_SG() in order to better address
IBLOCK and pSCSI. IBLOCK only allocates bios for ->map_data_SG(), and
pSCSI will allocate a struct request for both cases.
This patch fixes incorrect usage of ->map_task_SG() for all se_cmd descriptors
in transport_generic_new_cmd() by moving the call into it's proper location
directly inside of transport_allocate_data_tasks()
