Currently, get_scan_ratio() always calculate the balancing value for
global reclaim and memcg reclaim doesn't use it. Therefore it doesn't
have scan_global_lru() condition.
However, we plan to expand get_scan_ratio() to be usable for memcg too,
latter. Then, The dependency code of global reclaim in the
get_scan_ratio() insert into scan_global_lru() condision explictly.
This patch doesn't have any functional change.
