Vladimir Sementsov-Ogievskiy f24196d388 qcow2: qcow2_co_preadv: improve locking 
Background: decryption will be done in threads, to take benefit of it,
we should move it out of the lock first.

But let's go further: it turns out, that only
qcow2_get_cluster_offset() needs locking, so reduce locking to it.
