commit 7e3ae24832e0705583b1471febf3dc0eb1cc021f
Author: Paul Yang <kaishen.yy at antfin.com>
Date:   Mon Sep 30 14:05:31 2019 +0800

    Fix a bundle of mischecks of return values
    
    Several EVP_PKEY_xxxx functions return 0 and a negative value for
    indicating errors. Some places call these functions with a zero return
    value check only, which misses the check for the negative scenarios.
