Subject: [PATCH] Don't do global deinit when disabling TLS for a proxy back
 end connection

Prior to this commit, ssl_engine_disable called mgs_cleanup_pre_config
on the connection pool before returning:

mgs_cleanup_pre_config(c->pool);

mgs_cleanup_pre_config does not even touch the argument, as its
signature shows.

apr_status_t mgs_cleanup_pre_config(void *data __attribute__((unused)));

It does, however, deinitialize the global session cache and, more
importantly, the global GnuTLS data structures. Trying to use those
deinitialized data structures led to segmentation faults during TLS
handshake.

Since there is no reason to globally deinitialize GnuTLS when disabling
TLS for one specific proxy back end connection, the solution is to
simply remove the call to mgs_cleanup_pre_config from
ssl_engine_disable.
