linux-user: init_guest_space: Clean up control flow a bit

Instead of doing

        if (check1) {
            if (check2) {
               success;
            }
        }

        retry;

Do a clearer

        if (!check1) {
           goto try_again;
        }

        if (!check2) {
           goto try_again;
        }

        success;

    try_again:
        retry;

Besides being clearer, this makes it easier to insert more checks that
need to trigger a retry on check failure, or rearrange them, or anything
like that.

Because some indentation is changing, "ignore space change" may be useful
for viewing this patch.
