osmo_io: Improve handling and documentation of segmentation_cb

The read length is not needed in the segmentation callback, msgb
already has all the necessary information, the parameter previously was
just msgb_length(msg).

Also handle negative return values (except -EAGAIN) of the callback as
errors which cause the msg to be dropped. -EAGAIN will defer the msg.
