Subject: iwlwifi: mvm: don't restart HW if suspend fails with unified image

From: Luca Coelho <[email protected]>

commit bac453ab3745eaa64137ea6e77e009b45954f0ae upstream.

For unified images, we shouldn't restart the HW if suspend fails. The only reason for restarting the HW with non-unified images is to go back to the D0 image.
