e8c99bf813 scst: Simplify blk_make_request() and blk_map_kern_sg() 
For kernel versions >= 4.11.0, pass REQ_OP_SCSI_* as second argument
to blk_get_request() instead of READ or WRITE and setting REQ_OP_SCSI_*
later. For kernels < 4.11.0, instead of calling blk_rq_set_block_pc()
directly, call it indirectly through scsi_req_init().
