This isn't mentioned in the documentation for CRYPTO_ALG_ALLOCATES_MEMORY.  So
it's not part of the contract of CRYPTO_ALG_ALLOCATES_MEMORY currently.

Please don't make this change without updating the documentation.

If you'd like to make this change, please update the documentation for
CRYPTO_ALG_ALLOCATES_MEMORY to mention this additional exception.
