kmemleak: Reduce the false positives by checking for modified objects

If an object was modified since it was previously suspected as leak, do
not report it. The modification check is done by calculating the
checksum (CRC32) of such object.

Several false positives are caused by objects being removed from linked
lists (e.g. allocation pools) and temporarily breaking the reference
chain since kmemleak runs concurrently with such list mutation
primitives.
