kasan: Fix Software Tag-Based KASAN with GCC

[ Upstream commit 894b00a3 ]

Per [1], -fsanitize=kernel-hwaddress with GCC currently does not disable
instrumentation in functions with __attribute__((no_sanitize_address)).

However, __attribute__((no_sanitize("hwaddress"))) does correctly
disable instrumentation. Use it instead.
