A W=1 build with -Wenum-enum-conversion enabled, results in the
following build warning due to an arithmetic operation between different
enumeration types 'enum node_stat_item' and 'enum lru_list':
include/linux/vmstat.h:514:36: warning: arithmetic between different enumeration types ('enum node_stat_item' and 'enum lru_list') [-Wenum-enum-conversion]
514 | return node_stat_name(NR_LRU_BASE + lru) + 3; // skip "nr_"
| ~~~~~~~~~~~ ^ ~~~
Address this by casting lru to the proper type.
