virtblk_result returns blk_status_t which is a bitwise restricted type,
so we are not supposed to stuff it in a plain int temporary variable.
All we do with it is pass it on to a function expecting blk_status_t so
the generated code is ok, but we get warnings from sparse:
drivers/block/virtio_blk.c:326:36: sparse: sparse: incorrect type in initializer (different base types) @@ expected int status @@
+got restricted blk_status_t @@
drivers/block/virtio_blk.c:334:33: sparse: sparse: incorrect type in argument 2 (different base types) @@ expected restricted
+blk_status_t [usertype] error @@ got int status @@
Make sparse happy by using the correct type.
