Subject: [PATCH] KEYS: Create static version of public_key_verify_signature
The kernel test robot reports undefined reference to
public_key_verify_signature when CONFIG_ASYMMETRIC_PUBLIC_KEY_SUBTYPE is
not defined. Create a static version in this case and return -EINVAL.
Fixes: db6c43bd2132 ("crypto: KEYS: convert public key and digsig asym to the akcipher api")
