Stop exporting blk_rq_bio_prep
blk_rq_bio_prep is exported for use in exactly one place. That place can benefit from using the new blk_rq_append_bio instead. So - change dm-emc to call blk_rq_append_bio - stop exporting blk_rq_bio_prep, and - initialise rq_disk in blk_rq_bio_prep, as dm-emc needs it.
