[PATCH v4 07/12] compress/octeontx: remove unnecessary memset

[Stephen Hemminger <stephen@networkplumber.org>]

Calling memset before rte_free not necessary, and could be
removed by the compiler. In this case, the data is not security
sensitive so the memset can be removed. Some security scanning
tools will flag this.
