tcp: diag: add support for TIME_WAIT sockets to tcp_abort()

Browse source

Currently, "ss -K -ta ..." does not support TIME_WAIT sockets.

Issue has been raised at least two times in the past [1] [2]
it is time to fix it.

While we are at it, use inet_sk_state_load() while tcp_abort()
does not hold a lock on the socket.
