We now know that every of rbd_req_sync_op() passes an array of exactly one operation, as evidenced by all callers passing 1 as its num_op argument. So get rid of that argument, assuming a single op. Similarly, we now know that all callers of rbd_do_request() pass 1 as the num_op value, so that parameter can be eliminated as well.
