rhashtable: reset iter when rhashtable_walk_start sees new table

Browse Source 
The documentation claims that when rhashtable_walk_start_check()
detects a resize event, it will rewind back to the beginning
of the table.  This is not true.  We need to set ->slot and
->skip to be zero for it to be true.
