Subject: [PATCH] crypto: testmgr - extend acomp tests for NULL destination buffer
Date:   Fri, 12 Aug 2022 16:16:02 +0200

Acomp API supports NULL destination buffer for compression
and decompression requests. In such cases allocation is
performed by API.

Add test cases for crypto_acomp_compress() and crypto_acomp_decompress()
with dst buffer allocated by API.

Tests will only run if CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y.
