mm/compaction.c: avoid double mem_cgroup_del_lru()
del_page_from_lru_list() already called mem_cgroup_del_lru(). So we must
not call it again. It adds unnecessary overhead.
It was not a runtime bug because the TestClearPageCgroupAcctLRU() early in
mem_cgroup_del_lru_list() will prevent any double-deletion, etc.
