sctp: process sk_reuseport in sctp_get_port_local

Browse Source 
When socks' sk_reuseport is set, the same port and address are allowed
to be bound into these socks who have the same uid.

Note that the difference from sk_reuse is that it allows multiple socks
to listen on the same port and address.
