virtio-queue: fix clippy warnings on Rust 1.85

Our CI is being upgraded to Rust 1.85 and this will produce new warnings
from clippy like this one:

  error: this `map_or` can be simplified
      --> virtio-queue/src/queue.rs:313:19

       = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#unnecessary_map_or
       = note: `-D clippy::unnecessary-map-or` implied by `-D warnings`
       = help: to override `-D warnings` add `#[allow(clippy::unnecessary_map_or)]`
   help: use is_none_or instead

   313 ~         } else if desc_table
   314 +             .checked_add(desc_table_size).is_none_or(|v| !mem.address_in_range(v))

Apply the advice using `cargo clippy --fix`.
