Subject: [PATCH] bug 1953: removing possible SQL injections from
 C4::Acquisition::GetLateOrders

I decided to not make chagnes the the query that's executed on databases other than MySQL as I have no good way to test that.
This change provides no functinality change and requires no documentation change.
