ip: ip_options_compile() resilient to NULL skb route
commit c65353daf137dd41f3ede3baf62d561fca076228 upstream.
Scot Doyle demonstrated ip_options_compile() could be called with an skb
without an attached route, using a setup involving a bridge, netfilter,
and forged IP packets.
Let's make ip_options_compile() and ip_options_rcv_srr() a bit more
robust, instead of changing bridge/netfilter code.
With help from Hiroaki SHIMODA.
