[PATCH -next v2 4/7] mm/mglru: rename should_abort_scan to lru_gen_should_abort_scan

[Chen Ridong <chenridong@huaweicloud.com>]

From: Chen Ridong <chenridong@huawei.com>

The function should_abort_scan will be called in shrink_node_memcgs
to integrate shrink_many and shrink_node_memcgs. Renaming it to
lru_gen_should_abort_scan clarifies that it is specific to the
generational LRU implementation.
