[REBASE ON MERGE] Fix Incorrect mHighAddress Calculation (#484)

## Description

Fix an error made in the AdvLogger v5 PR (#471). This is the same fix
(but for a different variable name which is why it was mixed on the last
fix up) as #483.

Usage of mHighAddress (and mMaxAddress) will be evaluated as part of
issue #474.
