qcow2: Return 0/-errno in qcow2_alloc_compressed_cluster_offset()
qcow2_alloc_compressed_cluster_offset() used to return the cluster offset for success and 0 for error. This doesn't only conflict with 0 as a valid host offset, but also loses the error code. Similar to the change made to qcow2_alloc_cluster_offset() for uncompressed clusters in commit 148da7ea9d6, make the function return 0/-errno and return the allocated cluster offset in a by-reference parameter.
