The upstream commit 1771c6e1a567ea0ba2cccc0a4ffe68a1419fd8ef ("x86/kasan: instrument user memory access API") added KASAN instrument to x86 user memory access API, so added such instrument to ARM64 too.

Tested by test_kasan module.

Please, cover __copy_from_user() and __copy_to_user() too. Unlike x86, your patch doesn't instrument these two.
