Removes the dependency that this memzone reserve has on the
socket currently running on. Following the socket of the master
core will yield more predictable results when calling this
function after initialisation.

You don't describe what is the problem. In another mail, you say
"The original suggestion also fixes the crash that I was seeing because
of memory being reserved from a numa node with no "--socket-mem" allocated."
Please describe it clearly in the commit log.

You should also explain what this rte_memzone_reserve() is for,
and what are the incidences of your changes.

Thanks
