qcow2: Add refcount update reason to all callers

Enterprise / Virtualization / QEMU - Kevin Wolf [redhat.com] - 24 June 2013 03:25 UTC

This adds a refcount update reason to all callers of update_refcounts(), so that a follow-up patch can use this information to decide whether clusters that reach a refcount of 0 should be discarded in the image file.
