In case when get_image_offset() returns -1, we do zero out the
corresponding chunk of qiov. So, this should be reported as ZERO.
After block-status update, it never reports 0, so setting
unallocated_blocks_are_zero doesn't make sense. Drop it.
Same analysis as in patch 1 as to the lone two clients that cared, and
the fact that we are changing 'qemu-io -c map' output by reporting data
as allocated now. But I concur that as there is never a backing file,
the change is not a regression, but rather a bug fix.

While the commit message could be improved, the code change itself looks
correct.
