memcg: fix input of try_to_free_mem_cgroup_pages 

hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I9VO81



--------------------------------

The parameters for try_to_free_mem_cgroup_pages have been changed,
which was backported at 789303ae("mm: vmpressure: don't count
proactive reclaim in vmpressure"). However,
try_to_free_mem_cgroup_pages called in is_high_async_reclaim
was omitted, just fix it.

Fixes: 789303ae ("mm: vmpressure: don't count proactive reclaim in vmpressure")
