From: Daeho Jeong <daehojeong@google.com>
After releasing cblocks, the compressed file can be accidentally disabled in compression mode, since it has zero cblocks. As we are using IMMUTABLE flag to present released cblocks state, we can add IMMUTABLE state check when considering the compressed file disabling.
