[PATCH] ide:ide-cd: use q->initialize_rq_fn() to replace explicitly calling scsi_req_init()

[Hongxu Jia]

- memset(req->cmd, 0, BLK_MAX_CDB) is called once instead of twice.

- The sense buffer pointer gets initialized.

Fixes: 79d73346ac05 ("ide:ide-cd: fix kernel panic resulting from missing 
scsi_req_init")
