    sockets: in solisten_proto() don't call sbdestroy() on a PR_SOCKBUF
    
    A socket marked with PR_SOCKBUF has protocol specific socket buffers
    and will take care of the in its pr_listen method.  Right now we don't
    have any sockets that can listen and are PR_SOCKBUF, but that will
    change soon.
