Subject: Fix DEBUG_* compilation of qcow2.
Date: Thu, 04 Aug 2011 07:22:10 -0000
From: Philipp Hahn <hahn@univention.de>

Message-Id: <201108041922.11014.hahn@univention.de>
To: qemu-devel@nongnu.org

By introducing BlockDriverState compiling qcow2 with DEBUG_ALLOC and DEBUG_EXT
defined got broken.
Define a BdrvCheckResult structure locally which is now needed as the second
argument.

Also fix qcow2_read_extensions() needing BDRVQcowState.
