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. Reported-by: Frank Schuster <frank.schuster01@web.de> Signed-off-b: Vlad Yasevich <vladislav.yasevich@hp.com>
