Your doQuery function always returns null. You need to start by fixing that:
JavaScript
function doQuery(query, params = []) {
    return new Promise(function(resolve, reject) {
        db.query(query, params, function (err, rows, fields) {
            if (err) {
                reject(err);
            } else {
                resolve(rows);
            }
        });
    });
}
With that change in place, your other code should work - although you'll probably want to catch any errors thrown when you load the actions for an individual post, rather than throwing all of the posts away.

If your database supports it, you may also want to load the post actions in parallel, rather than serially:
JavaScript
async function loadPostActions(post, userid) {
    try {
        post.actions = await doQuery("SELECT * FROM posts_actions WHERE post_id = ? AND user_id = ? LIMIT 1", [post.id, userid]);
    } catch (error) {
        post.actionsError = error;
    }
}

async function getAllPosts(userid)
{
    try {
        const posts = await doQuery("SELECT * FROM posts ORDER BY id DESC");
        
        const actionPromises = [];
        for (let p = 0; p < posts.length; p++) {
            actionPromises.push(loadPostActions(posts[p], userid));
        }
        
        await Promise.all(actionPromises);
        return posts;
    } catch (error) {
        return error;
    }
}
