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.
