Currently, ndctl destroy-namespace -f all will output errors of the
form:
Error: destroy namespace: namespace0.0 failed to enable for zeroing, continuing
for any zero-sized namespace. That particular namespace looks like this:
{
"dev":"namespace0.0",
"mode":"raw",
"size":0,
"uuid":"00000000-0000-0000-0000-000000000000",
"sector_size":512,
"state":"disabled"
}
This patch skips over namespaces with size=0 when zeroing out info
blocks.
Fixes: 46654c2d60b70 ("ndctl/namespace: Always zero info-blocks")
