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.
