Subject: [PATCH] crypto: qat: remove unused and redundant pointer vf_info

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

The pointer vf_info is being assigned but never read, it is redundant
and therefore can be removed.

Cleans up clang warning: Value stored to 'vf_info' is never read

Fixes: ed8ccaef52fa ("crypto: qat - Add support for SRIOV")
