Subject: mm/kasan/common.c: fix compile error

I hit the following compile error in arch/x86/

   mm/kasan/common.c: In function kasan_populate_vmalloc:
   mm/kasan/common.c:797:2: error: implicit declaration of function flush_cache_vmap; did you mean flush_rcu_work? [-Werror=implicit-function-declaration]
     flush_cache_vmap(shadow_start, shadow_end);
     ^~~~~~~~~~~~~~~~
     flush_rcu_work
   cc1: some warnings being treated as errors
