transaction: clarify the "quick abort" scenario

Right now, the transaction has a code-pass to do a "quick abort" that skip most¹
(too much) of the logic when the right condition are detected²

We are about to improve this logic in multiple aspect. We clarify the code
first.

The conditional return in `_can_quick_abort` looks a bit weird because we are
about to make them more complex very soon.

[1] actually too much
[2] actually not often enough
