Subject: [PATCH] Fix error handling when calling "REQUIRES PRIVATE KEY"
 callback.

A recent patch in ssl.c introduced a callback for setting the
private key of the SSL context. This code contained a bug, which
resulted in lws_context_init_server_ssl() returning always
with a return value of 1, indicating an error.

This patch introduces the missing curly braces to fix the code's
intended behaviour.
