block: Use bdrv_has_zero_init_truncate()
vhdx and parallels call bdrv_has_zero_init() when they do not really
care about an image's post-create state but only about what happens when
you grow an image. That is a bit ugly, and also overly safe when
growing preallocated images without preallocating the new areas.
Let them use bdrv_has_zero_init_truncate() instead.
