sctp: Make sure we always return valid retransmit path
commit 4951feda0c60d1ef681f1a270afdd617924ab041
sctp: Do no select unconfirmed transports for retransmissions
added code to make sure that we do not select unconfirmed paths
for data transmission. This caused a problem when there are only
2 paths, 1 unconfirmed and 1 unreachable. In that case, the next
retransmit path returned is NULL and that causes a kernel crash.
The solution is to only change retransmit paths if we found one to use.
