I searched 4308fc58dced ("tcp: Document use of undefined variable") in

add a description about un-initialized value.

Even we don't use tmp_opt.sack_ok, I think it would be more safe to
initialize the value before using it. Just as other caller did.

Patch is not needed at all.

Comment and code are pretty clear.

This part of the code uses a generic function ( tcp_parse_options()) to
decode TCP options, but we are only caring about TS one.
