BUG/MINOR: ssl: returns when SSL_CTX_new failed during init

Browse Source 
In ssl_sock_initial_ctx(), returns when SSL_CTX_new() failed instead of
trying to apply anything on the ctx. This may avoid crashing when
there's not enough memory anymore during configuration parsing.

Could be backported in every haproxy versions
