[PATCH 4/4] Changes macro usage to avoid shadowing a variable.

From: Leonardo BrÃs
Date: Tue Oct 16 2018 - 20:09:52 EST


Changes the usage of DEF_FIELD_ADDR in this function to create a
reference and operate over it using an aux variable.
It also changes the loop logic used to find duplicates, to avoid
creating another variable.
