Subject: [PATCH] wireguard: avoid double unlikely() notation when using
IS_ERR()
commit 30ac4e2f54ec067b7b9ca0db27e75681581378d6 upstream.
The definition of IS_ERR() already applies the unlikely() notation
when checking the error status of the passed pointer. For this
reason there is no need to have the same notation outside of
IS_ERR() itself.
Clean up code by removing redundant notation.
