Subject: [PATCH] Taxonomy: Pass correct default value for `$post_id` to
 `wp_terms_checklist()` in the posts list table.

This matches the documented type of the `$post_id` argument and is consistent with other instances of `wp_terms_checklist()` calls.

Per the function documentation, the default value is integer `0`, not `null`.

Follow-up to [13535].

Props tareiking, donmhico, jrf.
Fixes #43639.
