encap_port in SCTP_INPUT_CB(skb) is used by sctp_vtag_verify() for
SCTP-over-UDP processing. In the GSO case, it is only set on the head
skb, while fragment skbs leave it 0.
This results in fragment skbs seeing encap_port == 0, breaking
SCTP-over-UDP connections.
Fix it by propagating encap_port from the head skb cb when initializing
fragment skbs in sctp_inq_pop().
Fixes: 046c052b47 ("sctp: enable udp tunneling socks")
