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.
