This reverts commit 656d8ace87.
The rational was: "If people don't have inventory, they will need a
backorder anyway and it's logical to not display the popup even
if the picking type has 'ask' for create backorder".
Also for the barcode application in OE we only show the reserved lines and
you could have the message if the picking was not fully reserve. Even if
you completed all the lines. So we could have a single flow for backend
and frontend.
But it's difficult for poeple to understand that the backorder is
base on the reservation and not on the initial demand. So we do a
step back. On top of it, people usualy won't mix flow. So they
could totaly use the "always create a BO" option on picking type
when they use the barcode and "ask" when they use the backend.
