Subject: [PATCH] nvme: tcp: remove redundant assignment to variable ret

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

The variable ret is being initialized with a value that is never read
and is being re-assigned immediately afterwards. The assignment is
redundant and hence can be removed.

Addresses-Coverity: ("Unused value")
