Check return value dst_key_getbool

Fix Coverity CHECKED_RETURN reports. Most cases we don't really
care about the return value but it is more strict to check it.

One case where 'dst_key_getbool' would return error we want to
behave the same as if it would succeed. Cast to void in this case
and add a comment.
