[pve-devel] [PATCH qemu-server] change check for write-zeros

[Dominik Csapak]

instead of hardcoding the storagetypes for writing zeros on a
backup restore, we use volume_has_feature with 'sparseinit'
for determining if we can omit writing zeros

please apply after my patch 'add sparseinit to has_feature'
