Subject: [PATCH net] crypto: chtls - Fix build error without IPV6

If IPV6 is not set, build fails:

drivers/crypto/chelsio/chcr_ktls.c: In function ‘chcr_ktls_act_open_req6’:
./include/net/sock.h:380:37: error: ‘struct sock_common’ has no member named ‘skc_v6_rcv_saddr’; did you mean ‘skc_rcv_saddr’?
 #define sk_v6_rcv_saddr __sk_common.skc_v6_rcv_saddr
                                     ^
drivers/crypto/chelsio/chcr_ktls.c:258:37: note: in expansion of macro ‘sk_v6_rcv_saddr’
  cpl->local_ip_hi = *(__be64 *)&sk->sk_v6_rcv_saddr.in6_u.u6_addr8[0];
                                     ^~~~~~~~~~~~~~~

Add IPV6 dependency to fix this.
