Log message:
	Attempt to fix intermittent failure with non-debug configured vgcfgbackup.
	
	There's an intermittent failure with vgcfgbackup that seems to have been
	introduced with the metadataignore / vgmetadatacopies patchset.
	Intermittent failures are often the result of uninitialized data,
	so this patch calls zalloc in a few places it might matter.
