ssl: Add the role (server or client) to the alert message

It is desirable to be as specific as possible in the info message, so
there can be no mistake if the alert is form the peer or generated by
us. This use to be an error message, but it is better to make it an
info message as sending an ALERT ending the connection is an expected
behaviour.
