crypto: atmel-ecc - avoid stale fallback key after set_secret failure

Browse source

Clear ->do_fallback before decoding a new ECDH secret and enable it only
after the software fallback accepts a caller-provided private key. This
avoids using a stale fallback key should crypto_kpp_set_secret() fail.
