[PATCH 2/8] block/vpc: return ZERO block-status when appropriate

[Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>]

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.
