- store cipher suite ID in a u64
- get rid of struct ieee802_1x_cp_conf: Instead of copying from kay to
a temporary struct, and then from the struct to the sm, just copy
from kay to cp.
- assign cs in ieee802_1x_mka_decode_dist_sak_body and reuse it
- cleanup of key allocation: ieee802_1x_kay_generate_new_sak and
ieee802_1x_mka_decode_dist_sak_body both allocate a struct key_conf,
fill it, and ask ieee802_1x_kay_init_data_key to allocate and set up
a struct data_key. They also allocate multiple key buffers and copy
the same data around. Stop moving data from buffer to buffer, and
just allocate what we really need.
