wireguard: notify key changes to crypto engine
This is a prerequisite patch for the following openssl API optimization patch, which tries to offload openssl ctx init and key expansion work to the initialization stage. Wireguard adds crypto keys via vnet_crypto_key_add (), and whenever it modifies the keys, the underneath openssl crypto engine shoud be informed of the changes to update the openssl ctx.
