mm/vmstat: revert "fix a W=1 clang compiler warning"

Commit 75b5ab134bb5 enabled -Wenum-enum-conversion in W=1 builds.  Commit
30c2de0a267c ("mm/vmstat: fix a W=1 clang compiler warning") fixed a
-Wenum-enum-conversion warning.  Commit 8f6629c004b1 removed the
-Wenum-enum-conversion option again from W=1 builds.  Since the W=1
compiler warning fix is no longer necessary, revert it.
