wifi: iwlwifi: pcie: simplify the resume flow if fast resume is not used

In most distributions, NetworkManager shuts the device down before
entering system suspend, so fast suspend is typically not used.

On older devices, resume currently tries to grab NIC access to infer
whether the device was powered off while suspended. That probe is only
meaningful for the fast-suspend path where the device is expected to
remain alive.

Unfortunately, for unclear reasons, grabbing NIC access was harmful as
reported in the bugzilla ticket below.

Workaround this issue by simply not grabbing NIC access if fast suspend
is not used.
