Before this patch, cancelling a PO of 2000 lines would take a **very,
very** long time to process... so long that I terminated it before it
finished... yikes.
This was due to the call to `_do_unreserve` on every single move when
calling `_action_cancel`, this meant that n² calls to unlink where being
made (at least), which also meant n² calls to
`stock.move._recompute_state` were being made... that's a lot of
recomputes... = bad performance
The patch simply calls unlink once, which means `_recompute_state` is
called only once, saving a lot of time.
Cancel time for a PO containing 2000 lines:
- Before patch: 1h30min+ (process terminated before finishing)
- After patch: 7min
Other modules making use of stock and `_action_cancel` should also see
benefits from this patch
