[SCSI] target: Fix SCF_SCSI_CONTROL_SG_IO_CDB breakage

This patch fixes a bug introduced during the v4 control CDB emulation
refactoring that broke SCF_SCSI_CONTROL_SG_IO_CDB operation within
transport_map_control_cmd_to_task().  It moves the BUG_ON() into
transport_do_se_mem_map() after the TRANSPORT(dev)->do_se_mem_map()
RAMDISK_DR special case, and adds the proper struct se_mem assignment
when !list_empty() for normal non RAMDISK_DR backend device cases.
