mm/vmstat: fix a W=1 clang compiler warning
[ Upstream commit 30c2de0a267c04046d89e678cc0067a9cfb455df ]
Fix the following clang compiler warning that is reported if the kernel is
built with W=1:
./include/linux/vmstat.h:518:36: error: arithmetic between different enumeration types ('enum node_stat_item' and 'enum lru_list') [-Werror,-Wenum-enum-conversion]
518 | return node_stat_name(NR_LRU_BASE + lru) + 3; // skip "nr_"
| ~~~~~~~~~~~ ^ ~~~
