Re: [PATCH] qemu: block copy: Propagate 'detect_zeroes' properly into mirror definition

'qemuDomainPrepareDiskSourceData' propagates 'detect_zeroes' only for the disk source image, but the mirror destination has the ambition to replace the disk source when the job is finished, so we need to propagate the 'detect_zeroes' setting also in that case. Unfortunately it would become very hairy to either set 'disk->mirror' sooner or propagate that we want this done into 'qemuDomainPrepareDiskSourceData', so the most straightforward solution is to do the propagation inside 'qemuDomainBlockCopyCommon'.
