SSL: server name callback changed to return fatal errors.

Notably this affects various allocation errors, and should generally
improve things if an allocation error actually happens during a callback.

Depending on the OpenSSL version, returning an error can result in
either SSL_R_CALLBACK_FAILED or SSL_R_CLIENTHELLO_TLSEXT error from
SSL_do_handshake(), so both errors were switched to the "info" level.
