crypto: ecdh_helper - Ensure 'len >= secret.len' in decode_key()
The length ('len' parameter) passed to crypto_ecdh_decode_key() is never
checked against the length encoded in the passed buffer ('buf'
parameter). This could lead to an out-of-bounds access when the passed
length is less than the encoded length.
Add a check to prevent that.
