This is just a clean code which simplify the code implement and make it
easy to understand. No logic changed from origin implement.
Make class_filter() inline which just return 0, and directly called from
verbose(), very_verbose(), HARDIRQ_verbose() and SOFTIRQ_verbose() without
macro control, remove unnecessary macros VERY_VERBOSE, HARDIRQ_VERBOSE
and SOFTIRQ_VERBOSE.
