Preliminary debugging seems to hint that wrong image convert status for
some sectors during iteration in convert_do_copy() accumulated a much
smaller allocated_sectors than it should.

Title:
  qemu-img convert malfunction on macOS

Status in QEMU:
  New

Bug description:
  On macOS 10.13.6, `qemu-img convert` failed to convert a qcow2 into a
  new qcow2 (for the purpose of shrinking the image).

  A 50GB (3.7GB allocated) qcow2 image was used as source. The qemu-img
  convert output was a 3.4MB file.

  qemu-img from HomeBrew were tested. Both 2.11.1 and 3.1.0_1 failed to
  convert a qcow2 image.
