There is a bug in the conversion code: if nbd_send_cmd() returns BLK_STS_RESOURCE, nbd_queue_rq() should return BLK_STS_RESOURCE instead of BLK_STS_OK. Fix this, move the conversion code into nbd_handle_cmd() and fix the remaining sparse warnings.

There is a bug in the conversion code: if nbd_send_cmd() returns BLK_STS_RESOURCE, nbd_queue_rq() should return BLK_STS_RESOURCE instead of BLK_STS_OK. Fix this, move the conversion code into nbd_handle_cmd() and fix the remaining sparse warnings.
