Pietro Borrello a4e9411769 sctp: sctp_sock_filter(): avoid list_entry() on possibly empty list 
commit a1221703a0f75a9d81748c516457e0fc76951496 upstream.

Use list_is_first() to check whether tsp->asoc matches the first
element of ep->asocs, as the list is not guaranteed to have an entry.

Fixes: 8f840e47f190 ("sctp: add the sctp_diag.c file")
