Eric Dumazet dd6a930314 sctp: read sk->sk_bound_dev_if once in sctp_rcv()
[ Upstream commit a20ea298071f46effa3aaf965bf9bb34c901db3f ]

sctp_rcv() reads sk->sk_bound_dev_if twice while the socket
is not locked. Another cpu could change this field under us.

Fixes: 0fd9a65a76e8 ("[SCTP] Support SO_BINDTODEVICE socket option on incoming packets.")
