Subject: [PATCH] cnic: remove redundant pointer req and variable func

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

Pointer req and variable func are being assigned but are never used
hence they are redundant and can be removed.

Cleans up clang warnings:
warning: variable 'req' set but not used [-Wunused-but-set-variable]
warning: variable 'func' set but not used [-Wunused-but-set-variable]
