liveupdate: Remove unused ser field from struct luo_session

The ser field in struct luo_session was intended to point to the
serialized data for a session, but it was never actually utilized in the
implementation. All serialization and deserialization logic consistently
uses the pointers maintained in struct luo_session_header.

Remove the dead field to clean up the structure.
