Subject: [PATCH] SSH-1: free mainchan_chan on destruction.

We went through the tree234 of ordinary channels freeing the thing at
the other end of each one, but of course in SSH-1 the main session
channel is not stored in that tree due to its totally different shape
in the protocol. So naturally I forgot to free _that_ one.
