libpuffs and libp2k both use the cookie to different structure, which now 

leads to struct p2k_node corruption now that libpuffs used pn_nlookup field
in struct puffs_node to avoid race conditions.

Attempt to fix that by adding a struct puffs_node at the beginning of struct
p2k_node. This seems to fix kern/46734
