crypto: inside-secure - make the key and context size computation dynamic
This patches makes the key and context size computation dynamic when using memzero_explicit() on these two arrays. This is safer, cleaner and will help future modifications of the driver when these two parameters sizes will changes (the context size will be bigger when using AEAD algorithms).
