[PATCH] mm: Rename mm_vmscan_lru_shrink_inactive trace event variables

[Kirill Tkhai]

Rename nr_activate{0,1} into nr_activate{anon,file} since this
is exported into userspace, e.g., it's shown here:

/sys/kernel/debug/tracing/events/vmscan/mm_vmscan_lru_shrink_inactive/format.

Now we have:
field:unsigned int nr_activate0;	offset:64;	size:4;	signed:0;
field:unsigned int nr_activate1;	offset:68;	size:4;	signed:0;

The patch changes these to:
field:unsigned int nr_activate_anon;	offset:64;	size:4;	signed:0;
field:unsigned int nr_activate_file;	offset:68;	size:4;	signed:0;

which is better readable.
