Good, I'm uploading another fix :
When the daemon runs while test your scenario you'll notice multipath won't load the map because it get a wwid
for the path from the daemon cache, which causes multipath to try to load a map *with* the faulty path ... which
fails in the kernel DM subsystem.
Fix is memseting pp->wwid in discovery.c:pathinfo() error path.
