sock_diag: allow concurrent operations

Browse source

sock_diag_broadcast_destroy_work() and __sock_diag_cmd()
are currently using sock_diag_table_mutex to protect
against concurrent sock_diag_handlers[] changes.

This makes inet_diag dump serialized, thus less scalable
than legacy /proc files.

It is time to switch to full RCU protection.
