Subject: [PATCH 20/36] sctp: remove useless start_fail from sctp_ht_iter in proc

From: Xin Long <[email-masked]>
Date: Mon, 27 Aug 2018 18:40:18 +0800

[ Upstream commit 834539e69a5fe2aab33cc777ccfd4a4fcc5b9770 ]

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")
