Subject: [PATCH] ieee802154: hwsim: remove redundant initialization of variable res

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

The variable res is being initialized with a value that is
never read and it is being updated later with a new value.
The initialization is redundant and can be removed.

Addresses-Coverity: ("Unused value")
