[Qemu-block] [PATCH v2 3/7] qcow2: Make perform_cow() call do_perform_cow() twice

Instead of calling perform_cow() twice with a different COW region each time, call it just once and make perform_cow() handle both regions. This patch simply moves code around. The next one will do the actual reordering of the COW operations. Signed-off-by: Alberto Garcia ---
