Fix the check for an empty send socket buffer on a TOE TLS socket.

Compare sbavail() with the cached sb_off of already-sent data instead of
always comparing with zero.  This will correctly close the connection and
send the FIN if the socket buffer contains some previously-sent data but
no unsent data.
