luo_session_deserialize() ignored the return value from
luo_file_deserialize(). As a result, a session could be left partially
restored even though the /dev/liveupdate open path treats deserialization
failures as fatal.
Propagate the error so a failed file deserialization aborts session
deserialization instead of silently continuing.
