SSL_CRL_PATH THROWS WARNING 1366

Problem:

The ssl_crl_path option was not set properly for
replication PS table. We have a temporary variable
where we have copied values and intended to
copy the temporary variable back to the crl_path.
Instead of memcpy(destination, source, len), the
code contained memcpy(detination, destination, len)
and hence the garbage value+warning.

Fix:

- Correct the memcpy() call.
- Made changes in the test accordingly.
- Minor cleanups in test.
