Jukka Laitinen 9d465615d1 src/drivers/sw_crypto: Fix buffer lengths for xchacha20 crypto
The size input argument for monocypher crypto_xchacha20_ctr should be the
plaintext message length.

The promise of the interface is, that the call to encrypt_data updates the
ciphertext message length after the call succeeds.

The crypto should check that the output buffer length (cipher length) is
large enough to contain the encrypted data.

Fix these issues; these have gone unnoticed for a long time since the interface
has been only used by logger, and passing the same size for both in and out.
