[PATCH V2 -next] netfilter: Use LOGLEVEL_<FOO> defines

[Joe Perches <joe@perches.com>]

Use the #defines where appropriate.

Miscellanea:

Add explicit #include <linux/kernel.h> where it was not
previously used so that these #defines are a bit more
explicitly defined instead of indirectly included via:
	module.h->moduleparam.h->kernel.h

Signed-off-by: Joe Perches <joe@perches.com>
---

I really don't want to get into unwinding all the
various #include dependencies.  kernel.h is pretty
generic and effectively used throughout the tree
to centralize various #includes.
