Add openssl error info

[Inokinoki]

Add macro and function to display openssl error info.

Before, during my debug, while private key validation failed, it shows:

Failed 'EC_KEY_check_key(key) - 1': -1 - LIBUSB_ERROR_IO

It may mislead someone who is debugging on the device.

Now it can show the right error information:

Failed 'EC_KEY_check_key(key) - 1': -1 - invalid private key
