mm: memcontrol: remove the pgdata parameter of mem_cgroup_page_lruvec
All the callers of mem_cgroup_page_lruvec() just pass page_pgdat(page) as
the 2nd parameter to it (except isolate_migratepages_block()). But for
isolate_migratepages_block(), the page_pgdat(page) is also equal to the
local variable of @pgdat. So mem_cgroup_page_lruvec() do not need the
pgdat parameter. Just remove it to simplify the code.
