Subject: [net 2/4] ice: Fix call trace on suspend

From: Anirudh Venkataramanan <anirudh.venkataramanan@...el.com>

It appears that the ice_suspend flow is missing a call to pci_save_state
and this is triggering the message "State of device not saved by
ice_suspend" and a call trace. Fix it.

Fixes: 769c500dcc1e ("ice: Add advanced power mgmt for WoL")
