UBUNTU: SAUCE: Revert "crypto: testmgr - add AES-CFB tests"

BugLink: https://bugs.launchpad.net/bugs/1841264
This reverts commit aae817ffb1146dbd8d9dd3b974508f20744a77a0.
This is causing build failures when crypto self tests are enabled
by un-setting CONFIG_CRYPTO_MANAGER_DISABLE_TESTS. This is because
this patch uses structure members that don't yet exist and are added
in a patch that Bionic doesn't have: 92a4c9fef34c "crypto: testmgr
- eliminate redundant decryption test vectors"

The missing patch is a large and error-prone backport which we have
decided to not accept at this time, therefore we will revert this
patch.
