block: add BLOCK_O_CHECK for qemu-img check
Image formats with a dirty bit, like qed and qcow2, repair dirty image
files upon open with BDRV_O_RDWR. Performing automatic repair when
qemu-img check runs is not ideal because the bdrv_open() call repairs
the image before the actual bdrv_check() call from qemu-img.c.
Fix this "double repair" since it leads to confusing output from
qemu-img check. Tell the block driver that this image is being opened
just for bdrv_check(). This skips automatic repair and qemu-img.c can
invoke it manually with bdrv_check().
Update the golden output for qemu-iotests 039 to reflect the new
qemu-img check output.
