[PATCH u-boot v2019.04-aspeed-openbmc 3/7] image: Return an error message from fit_config_verify_sig()

[Joel Stanley]

From: Simon Glass <sjg at chromium.org>

This function only returns an error message sometimes. Update it to always
return an error message if one is available. This makes it easier to see
what went wrong.
