Subject: [PATCH][next] iwlwifi: Fix error return on failed kmalloc

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

Currently the failing kmalloc sets package to the -ENOMEM error
return value however the error is returned by variable data. Fix this
by setting data to the error code instead.

Addresses-Coverity: ("Unused value")
Fixes: 9dad325f9d57 ("iwlwifi: support loading the reduced power table from UEFI")
