New function blk_req_append_bio
ll_back_merge_fn is currently exported to SCSI where is it used, together with blk_rq_bio_prep, in exactly the same way these functions are used in __blk_rq_map_user. So move the common code into a new function (blk_rq_append_bio), and don't export ll_back_merge_fn any longer.
