Andrew Hoang 26583f6aa8 Fix incorrect return code on ECDSA key verification 
ECDSA_do_verify() is a function that verifies a ECDSA signature given a hash and a public EC key. The function is supposed to return 1 on valid signature, 0 on invalid signature and -1 on error. Previously, we returned 0 if the key did not have a verify_sig method. This is actually an error case and not an invalid signature. Consequently, this patch updates the return code to -1.

Fixes #8766
