FIX error expedition qty 0

[BenjaminFlr]

When SHIPMENT_GETS_ALL_ORDER_PRODUCTS is enabled, if we have a qty set to 0 (because already sent or unavailable in current stock), it generates an error on creating the shipment, as GETPOST($qty, 'int') doesn't get any value when the field is disabled, whereas GETPOSTINT generates an integer.

It's linked to the following error:

dolibarr/htdocs/expedition/class/expedition.class.php

Line 2705 in a47f59c

$this->error = 'ErrorMandatoryParametersNotProvided';

@altairis-benjamin this needs an urgent FIX. You can't use GETPOSTINT to replace GETPOST($qty, 'int') or you loose any float value. For now users can't do a shipment with a decimal quantity. I am checking how to revert this and still fix your original issue
