ss: Remove checking SS_CLOSE state for packet and netlink

I dont see a reason that packet and netlink states will be
printed only if SS_CLOSE state is set in filter, in that case
to print states of netlink or packet sockets it is needed to run:

    ss -A netlink state close

instead of:

    ss -A netlink
