Subject: [PATCH] vmstat: Make NR_TLB_REMOTE_FLUSH_RECEIVED available even on UP

This fixes CONFIG_SMP=n, CONFIG_DEBUG_TLBFLUSH=y without introducing
further ifdef soup.  Caught by a kbuild bot randconfig build.

Fixes: ce4a4e565f52 ("x86/mm: Remove the UP asm/tlbflush.h code, always use the (formerly) SMP code")
