[SCSI] sg: fix iovec bugs introduced by the block layer conversion
- needs to use copy_from_user for iovec before passing it to
blk_rq_map_user_iov().
- before the block layer conversion, if ->dxfer_len and sum of iovec
disagrees, the shorter one wins. However, currently sg returns
-EINVAL. This restores the old behavior.
