Subject: [PATCH] examples/multi_process: fix received message length

[ upstream commit 0acd8ed3330a629658e3864d78a6bd4b78de321e ]

Simple_mp example receives message size less than 64 chars while send
side accepts chars less than 128, this leads to different result when
sending text length larger than 64.
This patch uses same buffer length on both message pool and command
line.

Fixes: af75078fece3 ("first public release")
