iwlwifi: warn if firmware image doesn't exist
If the firmware image that we attempt to load doesn't actually exist we have a broken firmware file or other code not checking things correctly, so warn in such a case. Also avoid assigning cur_ucode/ucode_loaded then. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
