sctp: add sock_reuseport for the sock in __sctp_hash_endpoint
This is a part of sk_reuseport support for sctp. It defines a helper
sctp_bind_addrs_check() to check if the bind_addrs in two socks are
matched. It will add sock_reuseport if they are completely matched,
and return err if they are partly matched, and alloc sock_reuseport
if all socks are not matched at all.
It will work until sk_reuseport support is added in
sctp_get_port_local() in the next patch.
v1->v2:
- use 'laddr->valid && laddr2->valid' check instead as Marcelo
pointed in sctp_bind_addrs_check().
