wifi: iwlwifi: don't warn if the NIC is gone in resume

Some BIOSes decide to power gate the WLAN device during S3. Since
iwlwifi doesn't expect this, it gets very noisy reporting that the
device is no longer available. Wifi is still available because iwlwifi
recovers, but it spews scary prints in the log.

Fix that by failing gracefully.
