slip: Buffer management (max_start_pad) fixes

Nothing in slip.c calls buffer_init for the first packet.  We don't
normally notice this because userv-ipif _both_ prints a confirmation
END byte right away, _and_ bookends packets with ENDs.

But this should be fixed.  Otherwise we fail an assertion when we try
to prepend things to the first data packet.
