Anatol Belski 261361c1b0 block: qcow_async: impl punch_hole and write_zeroes for QcowAsync
Deallocate clusters through QcowMetadata::deallocate_bytes, then
apply the resulting DeallocAction list (punch hole or write zeroes
at host offsets). write_zeroes delegates to punch_hole since
unallocated QCOW2 clusters inherently read as zero.
