mm_vmscan_{direct_reclaim_begin,wakeup_kswapd,lru_isolate,lru_shrink_active}
changed their output to the point where the script throws warnings and
errors. Update it to be properly in line with those changes.
Fixes: 3481c37ffa1d ("mm/vmscan: drop may_writepage and classzone_idx from direct reclaim begin template")
Fixes: 3b775998eca7 ("include/trace/events/vmscan.h: drop zone id from kswapd tracepoints")
