mm/vmscan: pass NULL to trace vmscan node reclaim

The tracepoint for node relcaims takes a `struct mem_cgroup *`
as the third argument, so pass NULL instead of 0 to fix warning
about using an integer as a pointer.

Fixes the following warnings:

mm/vmscan.c:6753:66: warning: Using plain integer as NULL pointer
mm/vmscan.c:6757:58: warning: Using plain integer as NULL pointer
mm/vmscan.c:7818:60: warning: Using plain integer as NULL pointer
