AEAD key parsing is duplicated to multiple places in the kernel. Add a
common helper function to consolidate that functionality.

Having enckeylen as a template parameter makes it a pain for hardware
devices that implement ciphers with many key sizes since each one would
have to be registered separately.
Since the authenc algorithm is mainly used for legacy purposes where its
key is going to be constructed out of two separate keys, we can in fact
embed this value into the key itself.
This patch does this by prepending an rtnetlink header to the key that
contains the encryption key length.
