Subject: [PATCH] crypto: chelsio: remove redundant premature assignment to iv

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

Variable iv is being assigned twice with the same value, the first
assignment is redundant and can be removed and instead keep the
latter assignment of iv as it is closer to the point it is being
used.

Addresses-Coverity: ("Unused value")
