mirror: Reduce I/O when destination is detect-zeroes:unmap
If we are going to punch holes in the mirror destination even for the
portions where the source image is unallocated, it is nicer to treat
the entire image as dirty and punch as we go, rather than pre-zeroing
the entire image just to re-do I/O to the allocated portions of the
image.
