fixed uninitialized variable

[sebastian-carpenter]

printAmt was not initialized to 0.

This never showed up before so I assume it is related to my configuration. printAmt is only uninitialized when there is no public or private key specified (hasPub, hasPriv). Which are set like this:

int hasPriv = (selection & OSSL_KEYMGMT_SELECT_PRIVATE_KEY) != 0;           
int hasPub = (selection & OSSL_KEYMGMT_SELECT_PUBLIC_KEY) != 0; 

I found this while building with the configuration specified in the documentation (Section 3.3.1 - 3.3.3)

OpenSSL:

git clone https://github.com/openssl/openssl.git
cd openssl
./config no-fips -shared
make
sudo make install

Good catch, thanks for the PR. This fix is also captured in #234, but that PR will take a bit longer.
