[dpdk-dev] [PATCH] app/compress-perf: fix memory deallocation issue

[Adam Dybkowski]

This patch fixes the memory deallocation issue which happened
after unsuccessful allocation (e.g. due to the out of memory)
and produced the segmentation fault.

Fixes: 424dd6c8c1 ("app/compress-perf: add weak functions for multicore test")
