Subject: [PATCH net] sctp: remove useless start_fail from sctp_ht_iter in proc

After changing rhashtable_walk_start to return void, start_fail would
never be set other value than 0, and the checking for start_fail is
pointless, so remove it.

Fixes: 97a6ec4ac021 ("rhashtable: Change rhashtable_walk_start to return void")
