mod_authn_socache.c: fix creation of default socache_instance.

In pre_config, default socache_provider is created, but socache_instance
initialization is missing. This leads to crash on startup if default
socache_provider is used (AuthnCacheSOCache is not called) and
AuthnCacheEnable or AuthnCacheProvideFor is used.

This problem has been introduced in r1531961.

A bug in some older versions of OpenSSL will cause a crash
in SSL_get_certificate for servers where the certificate hasn't
been sent.

Workaround by setting the ssl structure to client mode which
bypasses the faulty code in OpenSSL. Normally setting a server
ssl structure to client mode would cause problems later on:
but we are freeing the structure immediately without attempting
to use it.
