Generally we use 'unsigned long' for number of pages and 'u64' for
number of bytes. But function mem_cgroup_zone_nr_lru_pages and
mem_cgroup_node_nr_lru_pages use local variable whose type is 'u64'
to caculate numbers of pages, however, the return value type of funtion
which describes the numbers of pages is 'unsigned long'. Replace 'u64'
by 'unsigned long' in order to clean up this inconsistent.
