The 1st patch fixes a byte ordering issue where ctx->private_key is
currently passed to ecc_is_key_valid but the key is in reverse byte order.
To solve this issue it introduces the variable 'priv' that is already used
throughout the ecc and ecdh code bases for a private key in proper byte
order and calls the function with 'priv'.
The 2nd patch gets rid of the 'priv' variable wherever it is used to hold
a private key (byte-swapped initialized from ctx->private_key) in proper
byte order and uses ctx->private_key directly that is now initialized in
proper byte order.
