liveupdate: reject nonzero reserved value for SESSION_FINISH
The UAPI documents liveupdate_session_finish::reserved as requiring zero,
but luo_session_finish() currently ignores it and finishes the session.
Accepting nonzero values prevents the field from being safely repurposed
by a future extension.
Reject nonzero reserved values before changing session state, matching
LIVEUPDATE_SESSION_GET_NAME.
