image-fit-sig: Remove padding check
The padding algorithm is not mandatory for all signing algorithm.
For example, ECDSA does not require a padding method.
For RSA requiring PKCS padding, the belonging info->crypto(), assigned
with rsa_verify_key(), also has the check on the validity of info->padding().
Thus, remove the info->padding check from the upper, general layer.
