netfilter: xt extensions: use pr_<level> (2)
Supplement to 1159683ef48469de71dc26f0ee1a9c30d131cf89.
Downgrade the log level to INFO for most checkentry messages as they
are, IMO, just an extra information to the -EINVAL code that is
returned as part of a parameter "constraint violation". Leave errors
to real errors, such as being unable to create a LED trigger.
