Subject: [PATCH] loop: remove redundant assignment to err

From: Colin Ian King <colin.king@...onical.com>

The variable err is being assigned with a value that is never
read and it is being updated later with a new value.  The assignment
is redundant and can be removed.

Addresses-Coverity: ("Unused value")
