[IPVS]: Cleanup IP_VS_DBG statements.

From: Roberto Nibali <ratz@drugphish.ch>

The attached patch (against current -GIT) is a cleanup patch which does
following:

o lookup debug messages shifted back to 9
o added more informational value to flags and refcnt since those
entries can be in multiple referenced structures
o cleanup 80 char violation

It's the prepatch to the session pool implementation and helps very much
to debug and monitor important variables and structures regarding the
threshold limitation and persistency without the thousands of lookup
messages which noone is interested in.
