kmsan: compiler_types: declare __no_sanitize_or_inline
commit 90d1f14cbb9ddbfc532e2da13bf6e0ed8320e792 upstream.
It turned out that KMSAN instruments READ_ONCE_NOCHECK(), resulting in
false positive reports, because __no_sanitize_or_inline enforced inlining.
Properly declare __no_sanitize_or_inline under __SANITIZE_MEMORY__, so
that it does not __always_inline the annotated function.
