Subject: [PATCH resend] rhashtable: initialize all rhashtable walker members

Commit f2dba9c6ff ("rhashtable: Introduce rhashtable_walk_*") forgot to
initialize the members of struct rhashtable_walker after allocating it, which
caused an undefined value for 'resize' which is used later on.

Fixes: f2dba9c6ff ("rhashtable: Introduce rhashtable_walk_*")
