doc: clarify SSL_SESSION ownership in PSK use session callback
Document that when the psk_use_session callback is invoked multiple times
and wishes to return the same SSL_SESSION pointer, it must call
SSL_SESSION_up_ref() first since ownership is transferred on each call.
This prevents use-after-free errors from incorrect callback implementations.
