Fix two cmdq issues.

Changes in v2:

- Simplify the comment in patch #2 and check that `MSGQ_NUM_PAGES`
divides `1 << 32` (Alex). I used `%` since `is_multiple_of()` is out
due to MSRV.
- Add reviewed-by tags
- Link to v1: https://patch.msgid.link/20261111-msgq-64-pages-v1-0-d8c56b6fdd6c@xxxxxxxxxx
