calling ssh_disconnect means the Session object is still around
which means Channel objects may still be around,
but ssh_disonnects also performs ssh_channel_do_free on any open
channels, which makes those Channel._channel pointers dangling pointers.
This causes a UAF when Channel.__dealloc__ runs where (if the memory
wasn't reclaimed, which is likely) _channel->session is nulled
in the session->alive check in ssh_channel_free.

Because we can't fix this, this effectively means that Session.disconnect
CANNOT be implemented as an API. However, if we instead do the disconnect
in Session.__dealloc__, then this can't happen, as the Channel._session
reference forces Channel objects to be deallocd before the Session.

Another fix could be for ssh_channel_free to check both channel and
channel->session for NULL (currently does the former), but this would
only mask the crash in most instances and not actually fix the UAF.
