kasan: fix variable 'tag' set but not used warning

set_tag() compiles away when CONFIG_KASAN_SW_TAGS=n, so make
arch_kasan_set_tag() a static inline function to fix warnings below.

  mm/kasan/common.c: In function '__kasan_kmalloc':
  mm/kasan/common.c:475:5: warning: variable 'tag' set but not used [-Wunused-but-set-variable]
    u8 tag;
       ^~~
