sctp: fix oops while removed transport still using as retran path 

Since we can not update retran path to unconfirmed transports,
when we remove a peer, the retran path may not be update if the
other transports are all unconfirmed, and we will still using
the removed transport as the retran path. This may cause panic
if retrasnmit happen.
