Andrey Ryabinin 3f9ec80f7b arm64/kasan: don't allocate extra shadow memory
We used to read several bytes of the shadow memory in advance.
Therefore additional shadow memory mapped to prevent crash if
speculative load would happen near the end of the mapped shadow memory.

Now we don't have such speculative loads, so we no longer need to map
additional shadow memory.
