[Qemu-devel] [PATCH] block/qcow2: Use bdrv_truncate for size amend

[Max Reitz <mreitz@redhat.com>]

When amending the size option for a qcow2 image, use bdrv_truncate
instead of qcow2_truncate directly, since the latter will not adjust the
total_sectors count in the BDS structure (whereas the former will).
