Alexander Potapenko ac66998df3 Kconfig.debug: ensure early check for KMSAN in CONFIG_KMSAN_WARN ...

As pointed out by Masahiro Yamada, Kconfig picks up the first default
entry which has true 'if' condition.  Hence, the previously added check
for KMSAN was never used, because it followed the checks for 64BIT and
!64BIT.

Put KMSAN check before others to ensure it is always applied.
