bitbake: cache: Drop/simplify pointless type checking
Since we no longer have random data like version fields in these structures and we can assume any extra cache data subclasses our class, simplify the code. This is mostly reindenting after removal of the pointless type checks. (Bitbake rev: 5eb36278ac9975de1945f6da8161187320d90ba7) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
