Commitlog compression is coordinated externally, and it is safe to compress the same segment concurrently. Therefore, we can release the lock before starting the actual compression work, thereby avoiding to interfere with writes. Also, just ignore the currently active segment instead of panicking.

Commitlog compression is coordinated externally, and it is safe to compress the same segment concurrently. Therefore, we can release the lock before starting the actual compression work, thereby avoiding to interfere with writes.
Also, return an error if the mutable segment is requested to be compressed, instead of panicking.
