Subject: kasan: test: clean up ksize_uaf

Some KASAN tests use global variables to store function returns values so
that the compiler doesn't optimize away these functions.

ksize_uaf() doesn't call any functions, so it doesn't need to use
kasan_int_result.  Use volatile accesses instead, to be consistent with
other similar tests.
