RE: [PATCH] test/crypto: fix RSA decrypt op validation

[Gowrishankar Muthukrishnan <gmuthukrishn@marvell.com>]

Hi Kai Ji,
This patch adds a check on cop status after DECRYPT in existing RSA test.There are
few CI failures for this patch and the failures are very specific to Openssl 1.1.1 variants
used in below platforms:
* Ubuntu 20.04 - Openssl 1.1.1f
* RHEL 8 - Openssl 1.1.1k

When I manually build these Openssl variants in the above platforms (using
Docker images) and execute tests using respective openssl shared libraries,
all tests PASS. If I use Openssl library that is shipped within the above 
distributions, the test in patch FAIL.

I would like to get your opinion first to proceed on getting these patches CI acked.
In my debug, I don't see any issue with the patch and the patch adds better
Validation indeed. May be that, it has uncovered a potential failure in above
Distros. Can you check on your end if these failures disappear in manual try.
What would you suggest to go forward, for openssl PMD ?

If required, I can start filing a Bugzilla as well.

Thanks,
Gowrishankar
