I don't see where the cryptd request processing functions allocate memory.

It seems that cryptd should just inherit the flag, like most other templates.

Likewise for pcrypt.

And also likewise for rfc4309.

Where are you seeing the memory allocations that would require
CRYPTO_ALG_ALLOCATES_MEMORY to always be enabled for these?
