Correctly override equals and hashCode for our OpenSslSession sub-typ…

…es (netty#13829)

Motivation:

We did not correct override equals and hashcode methods for some of the
OpenSslSession implementations

Modifications:

Override methods

Result:

Be able to correctly understand if a session is equal or not
