Andrey Konovalov 219fc4b300 kasan: fix memory corruption in kasan_bitops_tags test
[ Upstream commit e66e1799a76621003e5b04c9c057826a2152e103 ]

Since the hardware tag-based KASAN mode might not have a redzone that
comes after an allocated object (when kasan.mode=prod is enabled), the
kasan_bitops_tags() test ends up corrupting the next object in memory.

Change the test so it always accesses the redzone that lies within the
allocated object's boundaries.
