In randconfig builds with sysfs, procfs and numa all disabled,
but SMP enabled, we now get a link error in the newly introduced
vmstat_refresh function:
mm/built-in.o: In function `vmstat_refresh':
:(.text+0x15c78): undefined reference to `vmstat_text'
This modifes the already elaborate #ifdef to also cover that
configuration.

Fixes: mmotm ("mm: /proc/sys/vm/stat_refresh to force vmstat update")
