commit 3e465fc3846734e9489273d889f19cc17b4cf4bd upstream.
This reverts commit d39083234c60519724c6ed59509a2129fd2aed41.
Because of recent interactions with developers from @umn.edu, all commits from them have been recently re-reviewed to ensure if they were correct or not.
Upon review, it was determined that this commit is not needed at all as the media core already prevents memory disclosure on this codepath, so just drop the extra memset happening here.
