Yes, good point. report_{hw,sw}_tags.c essentially define it, but it's
called by report.c code.

I think I suggested to make it a header first because there were still
parts that were report_{hw,sw}_tags.c specific, and the helper
function would be used by those 2 to build their version of
kasan_get_bug_type(), but that doesn't seem to be the case anymore.
