[PATCH 06/13] idiag: deprecate IDIAG_SS_* socket states

[Thomas Haller]

These values mirror TCP_* socket states from 'netinit/tcp.h'.
There is no good reason to expose a copy of those values.
User space should use the original values (if they care).
The only value that is actually useful is IDIAGNL_SS_ALL.
