inet_diag: allow concurrent operations
inet_diag_lock_handler() current implementation uses a mutex
to protect inet_diag_table[] array against concurrent changes.
This makes inet_diag dump serialized, thus less scalable
than legacy /proc files.
It is time to switch to full RCU protection.
As a bonus, if a target is statically linked instead of being
modular, inet_diag_lock_handler() & inet_diag_unlock_handler()
reduce to reads only.
