Could led to long delays when trying to establish connection to ethernet

sdp: BUG2141 - fix refcnt bug
This bug is reproducable when sdpnetstat(1) is run while a socket is being
destructed. sdp_proc utilities might try to hold a refcnt for a socket that its
destruction already began. This is possible because sdp_proc utilities uses
sock_list to scan for sockets, but a socket is removed from that list only
after all its resourcs are freed.
