[PATCH v2] mm: vmscan: drop zone id from kswapd tracepoints

[Yafang Shao <laoar.shao@gmail.com>]

It is not clear how is the zone id useful in kswapd tracepoints and the
id itself is not really easy to process because it depends on the
configuration (available zones). Let's drop the id for now. If somebody
really needs that information the zone name should be used instead.
