Arnd Bergmann a4336343ea kasan: add kasan_tag_mismatch prototype

commit fb646a4cd3f0ff27d19911bef7b6622263723df6 upstream.

The kasan sw-tags implementation contains one function that is only called
from assembler and has no prototype in a header.  This causes a W=1
warning:

mm/kasan/sw_tags.c:171:6: warning: no previous prototype for 'kasan_tag_mismatch' [-Wmissing-prototypes]
  171 | void kasan_tag_mismatch(unsigned long addr, unsigned long access_info,

Add a prototype in the local header to get a clean build.
