[EXT] [PATCH v3 2/4] app/test-compress-perf: allow test single compress operation

[Akhil Goyal]

> Part of the application options is to test only compress and only
> decompress but actually the application ignores this user option and
> tries to test always both compress and decompress.

>From the description it seems to be a bug in previous implementation.
Can we back port it? And update the patch title accordingly?
Also, release note update is not required for this fix.
