Subject: [PATCH] crypto: hisilicon: remove redundant assignment of pointer ctx

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

Pointer ctx is being re-assigned with the same value as it
was initialized with. The second assignment is redundant and
can be removed.

Addresses-Coverity: ("Unused value")
